Description

Technical Field

[0001] This utility model relates to the field of bridge construction tooling technology, and in particular to a hoisting tooling for a bridge wet joint construction template. Background Technology

[0002] In bridge construction, after the substructure is completed, precast bridge beams are erected first, followed by the installation of wet joint formwork in the cast-in-place joints between adjacent beams. Currently, the main method for installing wet joint formwork involves manual labor with simple lifting equipment. While suitable for lower bridge construction areas, this method is not suitable for higher bridge construction areas or areas with limited space. Furthermore, this method requires a significant amount of manpower and is slow in terms of installation speed, construction progress, and time.

[0003] To address the aforementioned issues, some construction companies have designed simplified hoisting fixtures for wet joint formwork. For example, the utility model patent CN212270686U, entitled "Machinery for Hoisting Wet Joint Formwork," primarily consists of a lower trolley, a hoisting system, and a hook. The hoisting system is fixed to the lower trolley, and its upper hoisting rope can move up and down. One end of the hook is fixed to the free end of the hoisting rope, and the other end is hooked to the reinforcing steel bars of the wet joint formwork to be assembled, allowing the formwork to be hoisted while the hoisting rope is being wound up. However, relying solely on a single hook to hoist the wet joint formwork makes it highly susceptible to swaying and falling during ascent, potentially leading to safety accidents.

[0004] Therefore, how to design a bridge wet joint formwork hoisting tool that is simple in structure, low in cost, reduces manpower, adaptable to various scenarios, fast in hoisting speed, short in construction period, stable in lifting and good in construction effect is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a hoisting tool for bridge wet joint construction formwork, which solves the technical problems of existing wet joint formwork hoisting, such as high manpower input, slow hoisting speed, long construction period, unstable lifting and poor construction effect.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a hoisting tool for construction template of bridge wet joint, wherein the gap between two adjacent beams is a cast-in-place wet joint that can be used to hoist the wet joint template, comprising: a first wheel frame, a second wheel frame, a first rope winding machine, a second rope winding machine, and a first and second lifting rope arranged in parallel.

[0007] The first wheel frame and the second wheel frame are distributed opposite to each other at both ends of the cast-in-place wet joint and both span across two adjacent beams.

[0008] The fixing part of the first rope winding machine is fixed to the first wheel frame, and its winding part rotates about an axis perpendicular to the height direction of the first wheel frame; the fixing part of the second rope winding machine is fixed to the second wheel frame, and its winding part rotates about an axis perpendicular to the height direction of the second wheel frame.

[0009] One end of the first lifting rope is detachably connected to the first wheel frame and the other end is fixed to the winding part of the second rope winding machine; one end of the second lifting rope is detachably connected to the second wheel frame and the other end is fixed to the winding part of the first rope winding machine; the wet joint template is placed on the first lifting rope and the second lifting rope so as to rise steadily as the first lifting rope and the second lifting rope are wound up simultaneously.

[0010] The beneficial effects of this utility model are: it improves the traditional structure of the formwork hoisting fixture for bridge wet joints. First, the first and second wheel frames are distributed at both ends of the cast-in-place wet joint, each spanning across two adjacent beams. Then, the fixing part of the first rope winding machine is fixed to the first wheel frame, and the fixing part of the second rope winding machine is fixed to the second wheel frame. Since one end of the first rope is detachably connected to the first wheel frame and its other end is fixed to the winding part of the second rope winding machine, and one end of the second rope is detachably connected to the second wheel frame and its other end is fixed to the winding part of the first rope winding machine, the rope can be wound simultaneously with the rotation of the winding parts of both the first and second rope winding machines. By retracting the first and second lifting ropes, manpower is reduced, and the wet joint formwork is steadily raised to the cast-in-place wet joint. This prevents the wet joint formwork from swaying during ascent, speeds up the ascent, shortens the construction cycle, and can replace crane hoisting. It is suitable for various construction areas (areas with limited working space or areas where the ground cannot be walked on). It also prevents the first and second lifting ropes from affecting the jointing work of the wet joint formwork (the first and second lifting ropes go around the bottom of the wet joint formwork instead of the sides, so when the sides of the wet joint formwork are spliced ​​with two adjacent beams and slabs, it will not affect the jointing work of the wet joint formwork), thus improving the hoisting construction effect.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the first rope winding machine, the second rope winding machine, the first lifting rope, and the second lifting rope are all multiple ropes arranged in a relatively opposite manner.

[0013] The further beneficial effect of using the above is that by using multiple first and multiple second ropes to lift the wet joint template simultaneously, the stability of the wet joint template during lifting can be improved, and accidents of abnormal falling of the wet joint template can be prevented.

[0014] Furthermore, the first wheel frame and the second wheel frame have the same structure and each includes a crossbeam, a fixed wheel axle, two support frames, two hand-held push rods, and two wheels; the two support frames are respectively placed on two adjacent beam plates; both ends of the crossbeam are respectively fixed to the two support frames; both hand-held push rods are arranged perpendicular to the crossbeam and are respectively fixed to the two support frames; the fixed wheel axle is arranged parallel to the crossbeam and its two ends are respectively fixed to the two hand-held push rods; the two wheels rotate at both ends of the fixed wheel axle and are respectively placed on two adjacent beam plates; the fixing part of the first rope winding machine is fixed to the crossbeam of the first wheel frame; the fixing part of the second rope winding machine is fixed to the crossbeam of the second wheel frame; one end of the first lifting rope is fixed to the crossbeam of the first wheel frame; one end of the second lifting rope is fixed to the crossbeam of the second wheel frame.

[0015] The further beneficial effect of using the above is that fixing the two reinforcing beams to the two support frames can not only improve the structural strength of the support frames and enhance the structural strength of the bridge wet joint formwork hoisting tool, but also facilitate the pushing of the first or second wheel.

[0016] Furthermore, the crossbeam, the fixed wheel axle, and the two hand-held push rods are all made of steel pipe.

[0017] Furthermore, the first and second rope winding machines have the same structure and both include a motor and a rotating wheel. The motor housing is either the fixing part of the first or second rope winding machine. The motor housing of the first rope winding machine is fixed on the first wheel frame, and its output shaft is arranged along the height direction perpendicular to the first wheel frame. The motor housing of the second rope winding machine is fixed on the second wheel frame, and its output shaft is arranged along the height direction perpendicular to the second wheel frame. The rotating wheel is either the winding part of the first or second rope winding machine, and the rotating wheel is drivenly connected to the output shaft of the motor. The other end of the first lifting rope is fixed on the rotating wheel of the second rope winding machine. The other end of the second lifting rope is fixed on the rotating wheel of the first rope winding machine.

[0018] Furthermore, the bottom surface of the wet joint template is provided with two limiting grooves; the first lifting rope and the second lifting rope are respectively placed in the two limiting grooves.

[0019] The further beneficial effect of using the above method is that placing the first and second lifting ropes in the two limiting grooves respectively can prevent the wet joint template from detaching from the first and second lifting ropes when it rises, thus avoiding danger.
