Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a cable-threadable mobile construction platform. Background Art

[0002] A cable-stayed bridge is a complex spatial hyperstatic structural system composed of three basic elements: cables, beams, and towers. Due to the immature design, construction, technology, and materials of the cable-stayed bridges built in the early stage, coupled with the poor maintenance management of the maintenance department during the operation stage, the existing cable-stayed bridges have been affected by human factors, environmental factors, and internal factors of structural materials. The main load-bearing materials of the existing cable-stayed bridges have aged and the structural bearing capacity has decreased. In particular, the cable components of the cable-stayed bridges are the most seriously damaged. When the cables are damaged, the bearing capacity of the cable-stayed bridge will be reduced. Therefore, replacing the cable has become a common method to extend the life of the cable-stayed bridge.

[0003] During the replacement of the inclined cables, it is often necessary to carry out construction work at the bottom of the beam. The project often uses a bridge inspection vehicle or makes fixed temporary tooling to carry out construction work at the bottom of the bridge. Since the cable replacement process takes a relatively long time, the use of a bridge inspection vehicle will incur a large construction cost. When a fixed temporary work platform is used for construction work, a crane is required to assist in lifting. At the same time, due to the obstruction of the inclined cables on the bridge deck, each time a cable is replaced, it is often necessary to use a crane to lift the entire cable to the next cable to be replaced. The construction process is mechanically cumbersome and requires a large number of workers, which brings great inconvenience to the construction work and seriously hinders the construction progress.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] For example, see Figure 1-4 As shown, the utility model is a kind of mobile construction platform capable of threading cables, comprising a first frame body 101 and a second frame body 102, wherein a counterweight block 2 is arranged in the first frame body 101, and a plurality of first protrusions are protruded outwardly from a side of the first frame body 101 close to the second frame body 102, and intervals are formed between the plurality of first protrusions; a second protrusion cooperating with the first protrusion is protruded outwardly from a side of the second frame body 102 close to the first frame body 101, and a connecting sleeve 7 is detachably provided between the first protrusion and the second protrusion, and the first frame body 101 is fixed to the second frame body 102 through the connecting sleeve 7, and a hole is provided on the connecting sleeve 7, and holes are vertically provided on both the first protrusion and the second protrusion, and insertion holes corresponding to the holes are provided on the connecting sleeve 7, and latches 8 are vertically inserted in the insertion holes and the holes;

[0022] It should be noted that the first frame 101 and the second frame 102 are combined to form a mobile frame 1 .

[0023] A moving device is disposed at the bottom of the first frame 101 , and winches 3 are disposed on both the first frame 101 and the second frame 102 . Corresponding traction ropes 10 are respectively wound around the two winches 3 .

[0024] The second frame 102 is also provided with a pulley 5 and a single pulley 6 .

[0025] A pin hole 4 having a diameter equal to that of the hole is provided on the first protruding portion near the hole.

[0026] Fixed pulleys 11 are provided at both ends of the bridge 12 , and traction ropes 10 are sleeved on the two fixed pulleys 11 .

[0027] Embodiment 2, a slidable bolt device of a mobile construction platform capable of being threaded through a cable is in a sliding state, such as Figure 3 As shown, at this time, the latch device has completely slid toward the counterweight part and is engaged with the latch hole 4 at that part, and the originally connected part already has a gap, which can pass through the inclined cable 9 that has an obstructive effect on the bridge deck.

[0028] A practical application of a mobile construction platform that can be worn through a cable, such as Figure 4As shown in the figure, the temporary tooling has been welded and spliced, and can provide a bridge bottom construction platform for construction workers;

[0029] After the construction is completed, there is no need to dismantle the temporary tooling. Relying on the traction provided by the winch 3, the movable pulley 5 and the single pulley 6, and the movable wheels are also arranged under the first frame 101, the movable wheels can also support the first frame 101 to move, so that the temporary tooling can move forward along the bridge deck; during the movement, the inclined cable 9 of the bridge deck will hinder the movement of the temporary tooling. At this time, the pin 8 of the slidable latch device can be pulled out, and the connecting sleeve 7 is pushed toward the counterweight block 2. Then, the pin 8 is installed back into the slidable latch device and fixed with the pin hole 4 at that part. The gap at the original connection will be exposed, and the temporary tooling continues to move forward to allow the inclined cable 9 to pass through the gap. Then, the slidable connecting sleeve 7 is returned to the gap, and the inclined cable 9 can pass through. The subsequent slidable latch device repeats this step, and finally the inclined cable 9 can pass through all the first protrusions and the second protrusions, and then continues to move along the bridge deck to the next bridge bottom construction site.
