The upper left side of the vertical frame is provided with at least three right spacer wheels along the front and back directions at the same height, and the right spacer wheels are in rolling contact with the right side of the viaduct.

On the left side of the lower part of the vertical frame, there are at least two layers of guardrail pipes along the front and back horizontal directions under the viaduct deck. There is a guardrail hinged on the page. When the guardrail is in a vertical state, the upper right side of the guardrail is connected to the slanting beam through the support rod. Guard railings are arranged vertically between the side and the platform.

By adopting the above technical scheme, when the present invention is in use, since the bridge deck is very smooth after pouring concrete, the compressed air storage tank provides power for the cylinder, and the cylinder drives the suction cup to press onto the bridge deck, so that the support frame can be stabilized. It is firmly fixed on the bridge surface, so as to avoid the heavy weight lifted by the hook at the right end of the boom, which will cause the supporting frame to tilt up and affect the safe construction. The right side of the boom extends to the right side of the viaduct, and if the application is set on the left side of the viaduct deck, the direction can be adjusted accordingly. The boom can be made of square steel pipes. The square steel pipes prevent rotation. The hooks are attached to heavy objects (construction equipment or construction materials), and the hoist can be used to transport the heavy objects down from the viaduct or hoist the heavy objects from the ground to the On the viaduct. During the upward transport of heavy objects, when the heavy objects are almost level with the bridge deck of the viaduct, the workers on the viaduct hold a long pole with a hook at one end to hook the hook and pull to the left, and then pull the heavy objects above the bridge deck of the viaduct. Several workers can remove the heavy objects from the hooks. At the beginning of the downward transport of heavy objects, the heavy objects on the bridge surface are first hung on the hook, and the long rod with a pull hook is used to hook the hook. Control the hoist to slowly drop the heavy object, and the long pole slowly moves the hook to the left to a stable state. In this process, use the long pole with the hook to stabilize the heavy object and slowly fall to avoid the heavy object from shaking violently. The large impact of the arm will affect the safe operation.

While lifting or lowering heavy objects, a hanging ladder hanger is provided on the front or rear side of the work platform, and the construction workers hang the hanging ladder on the hanging ladder hanger, and the construction workers can go up to it through the hanging ladder. On the work platform, the construction equipment and materials are lifted above the work platform by manipulating the winch, and the construction personnel place heavy objects on the work platform on the work platform. Construction workers are working on the bottom of the viaduct on the platform.

After a period of time, the air pressure in the suction cup will rise, start the exhaust motor, close the first air valve, open the second air valve, and the exhaust fan will pump air into the suction cup, thereby increasing the suction force of the suction cup and ensuring the safety of construction .

When the hoisting of heavy objects on a place on the bridge deck is completed, and the position of the work platform and the boom needs to be moved, the cylinder lifts the suction cup upwards, the motor reducer starts, and the driving support wheel moves on the bridge deck, and the left limit wheel also moves along the bridge deck. After the left side of the bridge deck guardrail base moves in place, the motor reducer stops, and the cylinder presses the suction cup to the bridge surface to position the application.

In the process of hoisting heavy objects, the left limit wheel also plays a strong supporting role to prevent the support frame from tilting to the right. The gravity of each equipment on the lower horizontal frame also plays the role of balancing the boom cantilever hoisting operation.

When the air pressure in the compressed air storage tank is not enough, the driving performance of the cylinder will be weakened, and the suction cup will not be firmly adsorbed to the bridge surface. At this time, it is necessary to close the second air pipe, open the first air valve, and the exhaust fan passes through the air. The booster valve stores air in the compressed air storage tank.

The diagonal brace is used to support the boom strength of the cantilever operation. The right limit wheel not only guides the movement along the viaduct, but also limits the stability of the vertical frame when lifting heavy objects. Rods provide foundation support.

The protective fence on the left side of the working platform can be dismantled when not in use, and then the protective fence is turned over on the working platform, which is convenient for the application to be removed from the viaduct or transferred to the left side of the viaduct for construction.

The reinforcing ribs play the role of strengthening the connection strength between the vertical frame and the upper horizontal frame, and the diagonal braces play the role of strengthening the strength between the vertical frame and the work platform, both of which improve the safety factor of construction on the work platform.

Diagonal brace beams and support rods are arranged on opposite sides of the work platform, which not only play a strengthening role, but also play a protective role.

Since the working platform (the hanging basket in the theme) is for the construction personnel to work, the working platform, the vertical frame and the upper horizontal frame are all fixedly connected. When only the bottom construction work of the viaduct is required, the boom and the components on the upper horizontal frame can be disassembled.

In the present invention, one end of the steel wire rope is pulled by a hoist, the other end of the steel wire rope passes through the U-shaped plate, and one end of the steel wire rope passing through the U-shaped plate is clamped on the stand with a U-shaped card to prevent the steel wire rope from loosening and achieve the ultimate goal. The role of insurance, then insert and install the third positioning pin and the fourth positioning pin on the U-shaped plate, insert the wedge-shaped plate into the U-shaped plate from top to bottom, use a hammer to hit the upper end of the wedge-shaped plate downward, and the left side of the wedge-shaped plate Both are in pressure contact with the third positioning pin and the fourth positioning pin, and the rear side of the wedge plate is in pressure contact with the bottom of the U-shaped plate through the steel wire rope. Because the rear side of the wedge-shaped plate and the inwall of the U-shaped plate are all provided with the anti-skid friction pattern that the steel wire rope is tightly crimped, the steel wire rope is stressed and pulls the wedge-shaped plate downward, so that the steel wire rope can be locked firmly.

The boom in the present invention can be adjusted in length according to the actual position. During adjustment, the manual positioning mechanism can be operated to loosen the boom, and then move the boom along the left and right directions. After the moving length of the boom is in place, then control the manual positioning mechanism to lock the boom. The specific control process is: the pin shaft below the handle rod is used as the rotating shaft to rotate upward. When the locking screw rotates to the vertical state, the right end of the handle rod is located in the U-shaped On the top of the washer, the other hand presses down the pressure plate, so that the rubber block on the lower surface of the pressure plate presses the handle rod downward, and then the handle rod is rotated to drive the locking screw to rotate. Since the locking screw is threadedly connected with the lower pin shaft, the rotation of the locking screw is Move the right end of the handle rod downward. When the right end of the handle rod is in contact with the U-shaped washer and it is laborious to turn the handle rod manually, release the hand pressing the pressure plate, and press the handle rod so that the pin shaft above the handle rod is the center line. Rotate left and right to make the bottom of the left end of the handle rod contact the upper surface of the pressure plate. Since the outer contour of the right end of the handle rod surrounds the center line of the upper pin shaft, it forms a gradually increasing arcuate surface structure of variable diameter from the upper part of the right side to the lower part of the left side. As the handle bar turns to the left, the outer contour of the right end of the handle bar will gradually press the pressure plate through the U-shaped washer, and several rubber blocks set on the lower surface of the pressure plate will further press the upper surface of the boom, so that the crane The arm is fixed securely. Finally, pull the hand-held part on the elastic pressing piece by hand to drive the elastic pressing piece to rotate horizontally with the fastening bolt as the centerline. The positioning hook presses down the upturned part of the handle bar tightly, which can ensure that the handle bar is fixed in place.

Since the top of the U-shaped gasket is provided with an arc-shaped groove corresponding to the structure of the variable-diameter arc surface and press-fitted, this structure can ensure that the locking stud will not move forward and break away from the U-shape when the handle rod does not move. Washers, so that the pressure plate firmly presses the boom, so that the boom and the supporting frame maintain an integral structure, thus achieving good safety and reliability.

The reinforcing ribs play the role of strengthening the connection strength between the front vertical board, the rear vertical board and the support beam, so as to ensure the reliability of positioning the boom. In addition, in order to increase the strength of the boom, that is, the lifting capacity, two square steel pipes can be welded side by side as a whole. Of course, it is necessary to properly adjust the distance between the front vertical board and the rear vertical board to place two square steel pipes.

To sum up, the present invention has reasonable design, simple structure, and each spare parts adopts the structure of separate assembly, which can be assembled as needed, has a certain lifting capacity, and has good fixing reliability on the bridge surface of the viaduct, and can be installed along the bridge. It is convenient and quick to install, especially for the boom, in order to facilitate handling and storage, it often needs to be disassembled after use. It can be locked and disassembled by the manual positioning mechanism, which is not only safe and reliable, but also quite convenient and quick. In a word, the present invention has multiple functions, not only can lift heavy objects, but also can construct the bottom surface of the viaduct, fully reduces the labor intensity of workers in road construction, improves work efficiency, and is safer and more reliable.

When the present invention is used in work, since the bridge deck is very smooth after pouring concrete, the compressed air storage tank 52 provides power for the cylinder 51, and the cylinder 51 drives the suction cup 55 to press onto the bridge deck, so that the support frame 1 can be stabilized. Be firmly fixed on the bridge deck, thereby avoiding the gravity of the heavy object hoisted by the suspension hook 19 at the right end of the boom 4 is too large to make the support frame 1 warp and affect the safe construction. Boom 4 right side stretches to the right side of viaduct 68, if the application is arranged on the left side of viaduct 68 bridge decks, direction corresponding adjustment gets final product. Boom 4 can adopt square steel pipe to make, and square steel pipe avoids rotating, and suspension hook 19 is articulated heavy object (construction equipment or construction raw material), and control winch 7 just can carry heavy object downwards from viaduct 68 or heavy object Hoist from the ground to the viaduct 68. During the upward transportation of the heavy object, when the heavy object is almost equal to the bridge deck of the viaduct 68, the worker on the viaduct 68 holds a long pole with a pull hook at one end to hook the hook 19 and pull it to the left to pull the heavy object to the bridge of the viaduct 68. After above the surface, several workmen will take off heavy object from suspension hook 19 and get final product. When the weight is transported downwards, the weight on the bridge deck is first hung on the hook 19, and the hook 19 is hooked with a long rod with a pull hook, and the hoist 7 is first manipulated to lift the weight upwards so that the weight leaves the bridge deck. Finally, the hoist 7 is controlled to slowly drop the weight, and the long pole slowly moves the hook 19 to the left to a stable state. The violent shaking of objects will have a large impact on the boom 4, which will affect the safe operation

While lifting or lowering heavy objects, a hanging ladder hanger 82 is provided on the front or rear side of the work platform 70, and the construction workers hang the hanging ladder on the hanging ladder hanger 82, and the construction workers can pass the hanging ladder.
