Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, in particular to a bridge wet joint template hoist. Background Art

[0002] In highway bridge construction, the construction of bridge wet joints usually adopts manual lifting to lift the formwork from the ground to the bridge deck. This lifting method is time-consuming, labor-intensive and has high labor costs. Alternatively, a simple electric hoist is used to pull and lift the formwork. However, the electric hoist needs to be connected to a cable and is not equipped with a protective cover, which can easily cause accidents such as entanglement and electric shock. In addition, the lifting of the wet joint formwork needs to be changed according to the installation location, and the electric hoist needs to be connected to a cable, which makes it inconvenient to move and the cable is more dangerous during the movement.

[0003] For example, CN219730323U "A wet joint formwork lifting device" includes two main trusses, the upper surfaces of the two main trusses are fixed with rack guides, the upper surfaces of the two rack guides are meshed with two traveling gears, the opposite sides of the traveling gears on the front and rear sides are rotatably connected to two mounting frames through bearings, a connecting block is fixed between the two mounting frames, the lower surface of the connecting block is fixed with a connecting plate, the lower surface of the connecting plate is fixed with an electric hoist, and the lower surfaces of the two main trusses are fixed with two traveling frames; they are moved by traveling wheels, and the main truss is the load-bearing beam of the electric hoist, which is used to support the weight of the electric hoist. The electric hoist uses the connecting block and the traveling gears on the front and rear sides to move left and right along the rack guides on the front and rear sides, thereby reducing manual labor and using mechanical lifting to reduce safety risks. However, the bridge wet joint formwork lifting device did not take into account the problem of slipping when lifting on a sloped bridge deck. Even if brakes are installed on the running wheels, when the bridge deck slope is greater than 2%, the brake fixity of the running wheels will be further weakened, and slipping will still occur. In addition, the electric hoist in the device is a suspended mobile type. During lifting, the formwork is very likely to shake, causing the hoisted objects to scatter. However, the device did not consider the installation of a device to prevent entanglement. When using the electric hoist for lifting, there is a risk of mechanical injury accidents when the wire rope is entangled. Summary of the Invention

[0026] like Figures 1-6As shown, the bridge wet joint formwork hoist includes a frame-shaped support frame 1, which is formed by a vertical support rod 11, a horizontal support rod 12 and a longitudinal support rod 13. The horizontal support rod 12 and the longitudinal support rod 13 form a rectangular frame and are arranged below the vertical support rod 11. The lower end of the vertical support rod 11 is provided with a roller 2 for driving the entire support frame 1 to move. The roller 2 is provided with a brake pedal 21 for fixing the equipment. The top of the vertical support rod 11 is provided with an operating platform 5. The operating platform 5 is provided with an electric hoist 3 for lifting the bridge wet joint formwork. Specifically, the operating platform 5 is provided with a The electric hoist installation slot 51 installed on the electric hoist 3 ensures the installation stability of the electric hoist 3 during the movement or operation of the bridge wet joint formwork hoist; the driving motor 33 of the electric hoist 3 is electrically connected to the power supply, specifically, it can be connected to the distribution box or the like by a cable; in order to facilitate the lifting wire 31 of the electric hoist 3 to pass through the operating platform 5 to lift the bridge wet joint formwork, a through hole 511 for the lifting wire 31 of the electric hoist 3 is opened on the operating platform 5; in order to adapt to the bridge deck with different slopes to lift the bridge wet joint formwork, it is avoided that the equipment slips due to the loose fixation of the brake pedal 21, and even the equipment is prevented from slipping due to the unstable center of gravity. In the event of an equipment overturning, telescopic legs 6 are provided at both ends of each transverse support 12, and the equipment is further fixed by setting the telescopic legs 6. Specifically, the telescopic legs 6 include a first telescopic sleeve 61 and a second telescopic sleeve 62; the top of the first telescopic sleeve 61 is set on the transverse support 12, and the first telescopic sleeve 61 and the transverse support 12 can be connected by welding or hinged connection, and it is only necessary to connect the first telescopic sleeve 61 with the support frame 1; the second telescopic sleeve 62 is slidably set in the first telescopic sleeve 61, and the second telescopic sleeve 62 slides along the length direction of the first telescopic sleeve 61, and then according to The length of the telescopic legs 6 is adjusted to accommodate different bridge deck slopes, keeping the operating platform 5 level and ensuring hoisting stability. To lock the relative position of the second telescopic sleeve 62 and the first telescopic sleeve 61, thereby fixing the height of the support frame 1 and allowing for subsequent template hoisting, the second telescopic sleeve 62 is provided with first positioning holes 621 arranged along its length. The lower end of the first telescopic sleeve 61 is provided with a first latch 611 that passes through the first telescopic sleeve 61 and the first positioning holes 621 in sequence. The first latch 611 is used to lock the second telescopic sleeve 62 with the first telescopic sleeve 61. To increase the contact area between the telescopic legs 6 and the ground and enhance equipment stability, a support base 63 is hinged to the bottom of the second telescopic sleeve 62, which is connected to the ground. To accommodate tilted bridge decks, the support base 63 is hinged to the bottom of the second telescopic sleeve 62, allowing the support base 63 to fully conform to the ground.Under normal hoisting conditions, that is, when the bridge slope is 1-2%, the brake pedal 21 provided on the roller 2 is used to fix the device. When the bridge slope is greater than 2%, the telescopic legs 6 can be opened, and the second telescopic sleeve 62 is slid away from the first telescopic sleeve 61, so that the support base 63 is in contact with the ground, and the operating platform 5 is adjusted to a horizontal position, and the second telescopic sleeve 62 and the first telescopic sleeve 61 are locked by the first latch 611 to ensure the height of the entire support frame 1 and the level of the operating platform 5; and each telescopic leg 6 can be individually extended and retracted to help the equipment reach a horizontal state, ensuring the hoisting stability of the entire bridge wet joint formwork hoist. Furthermore, an operating platform 5 is provided as the mounting platform for the electric hoist 3. When the operating platform 5 is adjusted to a horizontal state by retracting the legs 6, the electric hoist 3 is prevented from shifting during the hoisting process, and the hoisted objects are prevented from shaking and scattering. This bridge wet joint formwork hoist is suitable for both normal and steep slope bridge deck construction, can easily move or fix equipment, saves time and effort, and is adaptable to various construction scenarios. The electric hoist 3 is composed of a drive motor 33, a brake, a signal receiver, and a hoisting wire 31. The drive motor 33 has a rated lifting capacity of 350kg and a rated power of 1200W. The hoisting wire 31 has a diameter of 5mm, a length of 30m, and a towing capacity of 500kg. It is capable of hoisting wood and bamboo formwork, plywood, steel formwork, and the like. One end of the hoisting wire 31 is fixed on the electric hoist 3 , and the other end is provided with a hook 32 . The hook 32 includes a snap ring and an anti-unhooking block.

[0027] In order to facilitate the storage of the telescopic legs 6 when support is not required, and to adjust the angle between the telescopic legs 6 and the bridge deck to adapt to bridge decks of different slopes, to ensure the smooth lifting of the bridge wet joint template; Figure 5 、 Figure 6As shown, the telescopic leg 6 also includes a mounting seat 64 provided on the transverse support 12, the top of the first telescopic sleeve 61 is hinged to the mounting seat 64, and the mounting seat 64 is provided with second positioning holes 642 uniformly distributed along the circumference of the hinge point 641, and the first telescopic sleeve 61 is provided with a second latch 612 that sequentially passes through the first telescopic sleeve 61 and the second positioning hole 642; the end of the first telescopic sleeve 61 is connected to the transverse support 12 through the mounting seat 64, and the first telescopic sleeve 61 and the mounting seat 64 are hinged so that the first telescopic sleeve 61 can rotate around the hinge point 641. When the second telescopic sleeve 62 and the supporting base 63 rotate synchronously with the first telescopic sleeve 61, in order to lock the rotational position between the first telescopic sleeve 61 and the mounting base 64, a plurality of second positioning holes 642 arranged circumferentially around the hinge point 641 are provided on the mounting base 64. The first telescopic sleeve 61 is fixed by the second latch 612 which sequentially passes through the first telescopic sleeve 61 and the second positioning holes 642, thereby locking the position of the first telescopic sleeve 61 to adapt to bridge decks with different slopes and ensure the smooth lifting of the bridge wet joint formwork. When the height of the support frame 1 does not need to be adjusted by the telescopic legs 6, as shown in FIG. Figure 6 As shown, the first telescopic sleeve 61 is rotated to a position parallel to the horizontal support 12. At this time, the second telescopic sleeve 62 and the support base 63 are rotated synchronously with the first telescopic sleeve 61 to a position parallel to the horizontal support 12, and then the second pin 612 is used to pass through the first telescopic sleeve 61 and the second positioning hole 642 in sequence to lock the position between the first telescopic sleeve 61 and the mounting seat 64.

[0028] In order to facilitate the adjustment of the position of the telescopic leg 6 on the transverse support 12, when the length of the telescopic leg 6 is not enough to meet the adjustment range of the support frame 1, the position of the telescopic leg 6 on the transverse support 12 can be adjusted so that the telescopic leg 6 can meet the height adjustment range of the support frame 1; Figure 5 、 Figure 6 As shown, the mounting seat 64 is slidably set on the transverse support 12, and the mounting seat 64 is also provided with a locking member for locking the mounting seat 64; specifically, a through hole is opened on the mounting seat 64 for the transverse support 12 to pass through, so that the mounting seat 64 can move along the length direction of the transverse support 12, and then the mounting seat 64 is fixed at the corresponding position for use by a locking member (not shown in the figure). The locking member can use an existing buckle or pin to fix the mounting seat 64 on the transverse support 12.

[0029] In order to facilitate the operator to move the entire bridge wet joint formwork hoist, the roller 2 is connected to a full-copper motor for driving the roller 2 to rotate, and the full-copper motor is electrically connected to the power supply; by arranging a full-copper motor for driving the roller 2 to rotate on the roller 2, the full-copper motor (not shown in the figure) is arranged inside the roller 2, and its voltage is 48V and the speed is 5km / h; the above-mentioned roller 2 adopts a universal wheel with a wheel diameter of 150-200mm and a wheel width of 50mm, which can bear a load of 500kg; the roller 2 is directly driven to move by the full-copper motor, which avoids manual push and saves labor costs, and the full-copper motor can be connected to the remote control 7 signal that controls the movement of the lifting wire 31 of the electric hoist 3, and the remote control 7 is used to control the opening and closing of the full-copper motor, thereby driving the movement of the entire bridge wet joint formwork hoist.

[0030] In order to avoid the situation that when the bridge wet joint template hoist is moved, there are too many or too long cables connected between the electric hoist 3 and the power supply, which is inconvenient to move and has safety hazards, such as Figure 1 、 Figure 2 As shown, the power source is a battery 4, which is detachably arranged on the operating platform 5 and electrically connected to the electric hoist 3. The battery 4 is provided with a socket 41 for electrically connecting to the electric hoist 3. The battery 4 arranged on the operating platform 5 is used as the power source, and the socket 41 is directly provided on the battery 4, so that the power cord 34 of the electric hoist 3 can be directly connected to the battery 4, reducing the distance between the electric hoist 3 and the power supply, thereby reducing the length of the power cord 34 between the electric hoist 3 and the power supply, and no longer needing to use a cable connection to avoid the inconvenience of dragging the cable on the ground, so that the bridge wet joint formwork hoist is no longer restricted by the use distance of the distribution box, and uses a safe voltage to prevent electric shock accidents. The above-mentioned battery 4 is a detachable rechargeable battery 4. Specifically, a battery installation slot 52 for installing the battery 4 is provided on the operating platform 5 to ensure that during the movement or lifting of the bridge wet joint formwork hoist, the position of the battery 4 will not shift, resulting in an unstable connection of the power cord 34; the battery 4 uses a 48V80Ah lithium battery, and the capacity of the battery 4 is above 2-4 degrees to meet the output power of 2000W for 8 hours. Multiple batteries 4 can also be configured for use. A five-hole socket 41 and a one-button switch are set on the battery 4 to control the power transmission of the battery 4.

[0031] In order to facilitate the operator to operate the bridge wet joint template hoist without contact, Figure 2 As shown, the electric hoist 3 is electrically connected to a remote controller 7 for controlling the movement of the wire rope hook 32 of the electric hoist 3;

[0032] Furthermore, in order to facilitate the storage of the remote controller 7 and avoid the remote controller 7 being lost and unable to control the electric hoist 3, Figure 2 、 Figure 4 As shown, a storage slot 53 for placing the remote control 7 is provided on the operating platform 5; the remote control 7 needs to be taken out from the storage slot 53 when in use, and put back into the storage slot 53 when not in use to avoid loss.

[0033] To prevent the electric hoist 3 from being involved in an accident, the electric hoist 3, battery 4 and other electrical appliances should be protected from rain; Figure 1-Figure 4 As shown, the operating platform 5 is also provided with a cover 8, and the cover 8 is arranged above the operating platform 5; the cover 8 can be plugged into the operating platform 5, or can be connected to the operating platform 5 by bolts; by covering the operating platform 5 with the cover 8, the operator is isolated from the working electric hoist 3, avoiding accidents caused by the electric hoist 3 during operation, and the cover 8 can effectively isolate the external environment from the equipment inside the cover 8, avoiding the influence of rain, dust, etc. on the electric hoist 3, battery 4 and other electrical appliances, and ensuring the safety of the equipment during use. As a preferred method, in order to ensure the stability of the connection between the cover 8 and the operating platform 5, the cover 8 will not fall off during the operation or movement of the bridge wet joint formwork hoist; as Figure 1-Figure 4 As shown, one side of the cover body 8 is provided with a hinge 55 connected to the operating platform 5, and the side of the cover body 8 away from the hinge 55 is provided with an extension portion 81 for locking with the operating platform 5, and the operating platform 5 is provided with a plug hole 54 for the extension portion 81 to pass through, and a connecting hole 82 is provided on the extension portion 81. A connecting piece 83 is provided in the connecting hole 82 to pass through the connecting hole 82 and abut against the bottom of the operating platform 5 to lock the cover body 8 and the operating platform 5; the cover body 8 and the operating platform 5 are connected by the hinge 55, which is convenient for the operator to quickly open the cover body 8 when in use and close the cover body 8 when not in use. The number of hinges 55 between the cover body 8 and the operating platform 5 can be selected according to the length of the connecting edge; in order to ensure the stability of the cover body 8 buckled on the operating platform 5, as shown in FIG. Figure 3 、 Figure 4 As shown, an extension portion 81 for locking with the operating platform 5 is provided on the side of the cover body 8 away from the hinge 55, and a plug hole 54 corresponding to the extension portion 81 is provided on the operating platform 5. When the cover body 8 needs to be buckled on the operating platform 5, the extension portion 81 passes through the plug hole 54, so that the cover body 8 and the operating platform 5 are buckled. A connecting hole 82 is provided on the extension portion 81, and a connecting member 83 is provided in the connecting hole 82 to abut against the bottom of the operating platform 5 to lock the cover body 8 and the operating platform 5. The extension portion 81 is locked by the connecting member 83 to prevent the extension portion 81 from moving out of the plug hole 54, thereby ensuring the stability of the connection between the cover body 8 and the operating platform 5; the above-mentioned connecting member 83 can adopt an existing pin, bolt or lock, and is locked by the lock. It can be locked when the bridge wet joint formwork hoist stops working to prevent the electric hoist 3, battery 4, remote control 7 and other equipment on the operating platform 5 from being lost.

[0034] In order to ensure that the bridge wet joint formwork hoist has high strength while reducing the overall weight as much as possible for easy movement, the cover 8 is made of steel plate with a wall thickness of 2mm, the operating platform 5 is made of steel plate with a wall thickness of 5mm, and the support frame 1 is made of φ45×3mm seamless round steel pipe; the bridge wet joint formwork hoist made of the above materials has a total weight of 71.2kg. Compared with similar equipment, the equipment has been integrated and lightweight, and it is more convenient and quick to use. The support frame 1 is made of φ45*3mm seamless round steel pipe. The bearing capacity of a single round steel pipe can reach more than 900KN, which has the advantages of strength, high quality and lightness, further reducing the overall weight and facilitating the movement of the machine.

[0035] The present invention provides a bridge wet joint formwork hoist having the following working principle:

[0036] The battery 4 is used as a power source to ensure stable power while fundamentally eliminating the occurrence of electric shock accidents; in actual operation, an all-copper motor is provided on the roller 2 to drive it to move, and the all-copper motor is connected to the remote control 7 signal. The remote control 7 controls the movement of the roller 2, so that an operator can control the mobile device through the remote control 7. At the same time, a brake pedal 21 is provided on the roller 2 to be fixed during operation. When the bridge wet joint formwork hoist is hoisting the bridge wet joint formwork on a bridge surface with a slope greater than 2%, the fixity of the brake pedal 21 of the roller 2 will be further weakened. At this time, the telescopic legs 6 can be opened, and the support base 63 of the telescopic legs 6 directly contacts the bridge surface to increase the stability of the equipment. By adjusting the length between the second telescopic sleeve 62 and the first telescopic sleeve 61, the height of the entire device can be adjusted. Each telescopic leg 6 can be retracted individually to help the equipment reach a horizontal state. Compared with traditional brackets that require more than two people to lift and move, the number of operators can be reduced from two to one, while reducing the workload of workers. All electrical equipment of the present invention are installed on the operating platform 5, and a cover 8 is provided to protect all electrical equipment from the sun and rain to extend the life of the equipment. After the electric hoist 3 and the battery 4 are installed and fixed, the power cord 34 of the electric hoist 3 is directly inserted into the socket 41 of the battery 4 and the power of the battery 4 is checked to see if it meets the construction requirements. If the power of the battery 4 does not meet the requirements, the battery 4 is replaced or charged. If the power of the battery 4 meets the requirements, the cover 8 is first buckled and the battery 4 is turned off with one button. The bridge wet joint template hoist is moved to the required lifting position. After the equipment is adjusted into place, the brake pedal 21 of the roller 2 is adjusted to the locked state. At this point, open the cover 8, remove the remote control 7 from the operating platform 5, turn on the battery 4, and then snap the cover 8 closed. The equipment is now in standby mode. Press the down button on the remote control 7 to lower the lifting wire 31 and hook 32 on the electric hoist 3. After lowering them into place, hang the template to be hoisted on the hook 32 and ensure that the anti-unhooking device of the hook 32 is intact. Press the up button on the remote control 7 to lift the template. The entire operation process only requires one person to operate the equipment and one person to hang the template. After the operation is completed, retract the hook 32, return the remote control 7 to the operating platform 5, and then turn off the battery 4 with one button. Finally, snap the cover 8 closed and lock it.
