Description

Technical Field

[0001] This utility model relates to the field of precast box girder technology for bridge engineering, and in particular to a detachable movable template. Background Technology

[0002] In bridge engineering, the beams to be hoisted from the bottom need to have a reserved slot set on the beam fabrication platform so that the wire rope can pass through from the bottom and lift the beam from the beam fabrication platform to the storage area. A bottom formwork needs to be set at the reserved slot position. The current common practice is to use sand boxes or steel plates with square timber support underneath, which makes it inconvenient to pass the wire rope through the hoisting hole before hoisting the box girder.

[0003] Existing technologies, such as Chinese Patent Publication No. CN204728690U, disclose a simple detachable movable template, including a main frame and an adjustable movable template mounted above the main frame. The main frame includes a pair of symmetrically arranged main beams, which are fixedly connected in the middle by a tie beam. Each end of the two main beams is equipped with a height adjustment device for adjusting the height of the movable template, which contacts the movable template. Support legs are symmetrically arranged at the bottom of the main beams, forming a height-adjustable "stool-type" structure. At the pre-reserved slot for precast beam hoisting, the stool height is lowered before the box girder is hoisted, the movable template is lowered, and a steel wire rope is passed through the hoisting hole to hoist the box girder. Compared to the previous method of hoisting the movable template and box girder together to the platform and then retrieving the movable template, this saves labor costs and template wear, significantly reducing labor and template investment. However, this utility model requires rotating multiple bolts and bolt locks during use, making adjustment time-consuming and labor-intensive, and it lacks measures to secure the movable template, making it prone to displacement.

[0004] To address the issue of the inconvenience of quickly and effortlessly adjusting the height of the formwork used in bottom-lifting of the box girder, existing technologies, due to the difficulty in adjusting the height of the formwork, make it difficult for the wire rope to pass through the lifting hole for bottom-lifting of the box girder. As a result, the formwork and box girder are directly lifted to the platform together and then retrieved, which is labor-intensive and requires a lot of formwork. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the templates used in the bottom hoisting of beams in the prior art are not easy to adjust in a quick and labor-saving manner, and to propose a detachable movable template.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a detachable movable template, comprising a base, a support column, a sleeve, a movable template, and an adjustment mechanism, wherein the support column is fixedly connected to the surface of the base, the sleeve is sleeved and connected to the surface of the support column, the movable template is fixedly connected to the surface of the sleeve, and the adjustment mechanism is disposed on the base; The adjustment mechanism includes a limiting groove, which is formed on the top surface of the base. A bidirectional threaded rod is rotatably connected in the limiting groove. A worm is rotatably connected to the inner wall of the base. A worm wheel is fixedly connected to the surface of the bidirectional threaded rod, and the worm wheel meshes with the surface of the worm. The surface of the bidirectional threaded rod is threadedly connected to a movable block, which is slidably connected to the surface of the limiting groove. A connecting rod is rotatably connected to the surface of the movable block, and an adjusting plate is rotatably connected to the end of the connecting rod away from the movable block. The adjusting plate is slidably connected to the surface of the support column.

[0007] Furthermore, the surface of the adjusting plate is provided with a slot, the sleeve is inserted into the surface of the slot, and both the surface of the adjusting plate and the movable template are provided with through grooves.

[0008] Furthermore, a handle is fixedly connected to the surface of the worm gear, and scale lines are formed on the surface of the support column. The scale lines are in multiple sets and are evenly distributed.

[0009] Furthermore, the number of the support, sleeve, and slot is four sets, and the number of the movable block and connecting rod is two sets.

[0010] Furthermore, the surface of the adjusting plate is provided with a disassembly and assembly mechanism, the disassembly and assembly mechanism includes a bracket, the bracket is fixedly connected to the surface of the adjusting plate, an insert rod is slidably inserted on the bracket, a pull plate is fixedly connected to the surface of the insert rod, an insertion hole is opened on the surface of the adjusting plate, and a positioning hole is opened on the surface of the sleeve.

[0011] Furthermore, the insertion rod is inserted into the surface of the insertion hole, and the insertion rod is inserted into the surface of the positioning hole. The bracket, insertion rod, pull plate, insertion hole and positioning hole are all in two sets, and each set contains two insertion rods, insertion holes and positioning holes.

[0012] Furthermore, a tension spring is sleeved and connected to the surface of the insertion rod. One end of the tension spring is fixedly connected to the surface of the bracket, and the other end of the tension spring is fixedly connected to the surface of the pull plate. A groove is formed on the surface of the pull plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting an adjustment mechanism, the movable template is inserted into the slot along the support column using a sleeve. Then, by holding the handle and rotating the worm gear, the worm wheel drives the bidirectional threaded rod to rotate, causing the two sets of movable blocks to move towards or away from each other along the limiting groove. Then, the connecting rod drives the adjustment plate to move up and down along the support column, thereby adjusting the height of the movable template. The self-locking effect of the worm gear and worm wheel prevents the movable template from moving arbitrarily. By setting an adjustment mechanism, the height of the movable template can be adjusted conveniently and labor-savingly. The movable template is lowered before the box girder is hoisted, making it easier for the wire rope to pass through the hoisting hole to hoist the box girder. Compared with the traditional method of hoisting the template and box girder together to the platform and then retrieving them, it saves labor costs and template damage, thus effectively improving the applicability of the equipment.

[0014] 2. In this utility model, by setting up a disassembly and assembly mechanism, in order to avoid relative movement between the movable sleeve and the slot, a rod can be inserted into the insertion hole and the positioning hole to fix the movable template and the adjusting plate relatively. When it is necessary to disassemble or assemble the movable template, simply hold the two sets of pull plates at the groove, pull the pull plates to disengage the rod from the positioning hole and tighten the tension spring to remove the movable template. After inserting the movable template into the slot along the support column using the sleeve, release the pull plates. Under the rebound action of the tension spring, the rod returns to its original position and is inserted into the positioning hole to fix the movable template. By setting up a disassembly and assembly mechanism, the movable template can be disassembled and assembled conveniently and effortlessly, and the displacement of the movable template can be avoided, thus effectively improving the convenience of the equipment.
