[0002] Ladder structures are often used in the construction of high piers for highways and urban viaducts, allowing workers to climb the ladders to carry out construction work.

[0003] When carrying out high-rise operations, there are often dismantled waste materials or other debris that need to be unloaded from the ladder platform in a timely manner to reduce the weight of the platform and prevent them from occupying the space of the ladder platform.

[0004] Existing unloading methods include: first, loading the debris into a bucket and slowly lowering it to the ground with a rope; second, directly throwing the debris onto the ground; third, manually removing the waste, which is labor-intensive and slow.

[0005] Therefore, a new safety ladder for bridge pier construction is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this utility model is to propose a safe climbing ladder for the construction of high bridge piers, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, one embodiment of the present invention provides a safety ladder for the construction of high bridge piers, comprising two sets of ladder frames, wherein a plurality of treads are fixedly connected to the inner side of the ladder frames, and a construction platform is fixedly connected between the top ends of the ladder frames, and the two sets of ladder frames are connected by a crossbeam. The bottom of the ladder is equipped with casters, and the surface of the ladder and the top surface of the construction platform are fixedly connected with guardrails. The side of the ladder frame is fitted with hinges, and a sliding plate is movably connected to the side of the ladder frame via the hinges. A baffle is fixedly connected to the edge of the sliding plate surface. A connector is detachably connected to the edge of the bottom surface of the skateboard, and one side of the connector is detachably connected to the ladder frame.

[0009] Preferably, in any of the above schemes, the two sets of ladder frames are symmetrical about the mid-plane of the construction platform, and the ladder frames are welded to the footboards.

[0010] The above technical solution is adopted: This device is specially used for the construction of high piers of viaducts and highway bridges. Specifically, construction workers climb onto the construction platform by ladder to carry out the construction.

[0025] like Figure 1-4 As shown, the safety ladder for the construction of the high pier of this bridge includes two sets of ladder frames 1. Several steps 2 are fixedly connected to the inner side of the ladder frame 1. A construction platform 3 is fixedly connected between the top of the ladder frame 1. The two sets of ladder frames 1 are connected by a crossbeam 4. The bottom of the ladder frame 1 is equipped with casters 5, and the surface of the ladder frame 1 and the top surface of the construction platform 3 are fixedly connected with guardrails 6; A hinge 7 is installed on the side of the ladder frame 1, and a slide plate 8 is movably connected to the side of the ladder frame 1 via the hinge 7.

A connector 10 is detachably connected to the edge of the bottom surface of the skateboard 8, and one side of the connector 10 is detachably connected to the ladder frame 1.

[0026] Example 1: Two sets of ladder frames 1 are symmetrical about the mid-plane of the construction platform 3, and the ladder frames 1 are welded to the footboards 2. This device is specifically used for the construction of high piers of viaducts and highway bridges. Specifically, construction workers climb the ladders to the construction platform 3 to perform their work. The construction platform 3 is connected to the top of the ladder frames 1 by bolt and nut assemblies, and the casters 5 integrate brakes. This device consists of five parts; the first part is the ladder section, composed of the ladder frames 1 and footboards. The second part is construction platform 3, which consists of construction platform 3; The third part is guardrail 6, which consists of guardrail 6; the fourth part is the moving mechanism, which consists of casters 5 and brakes on them. The fifth part is the newly added mechanism, which consists of hinge 7, slide plate 8, baffle 9, connector 10 and the connection structure of connector 10.

[0027] Example 2: The guardrail 6 and the ladder frame 1 are connected by bolts and nuts. The guardrail 6 is a single-sided design. This device can be moved on the ground via casters 5. The sliding plate 8 can rotate 90 degrees and is made of stainless steel. The top of the sliding plate 8 extends to the construction platform 3. The connector 10 is L-shaped and is connected to the sliding plate 8 by hexagonal socket head cap screws.

[0028] The working principle of this utility model is as follows: Move this device to the construction position, rotate the slide plate 8, and when the slide plate 8 is flush with the ladder frame 1, install the connector 10 through the hex bolts. The connector 10 is used to connect the slide plate 8 and the ladder frame 1 to fix the slide plate 8. Workers climb onto construction platform 3 using ladders. The side of the slide plate 8 is the construction side. Waste, scrap, and dismantled or replaced parts generated during the construction of the bridge piers can all slide down to the ground via the slide plate 8. There is no need for workers to manually carry the waste down, no need for workers to throw the waste and create danger, and no need for workers to hoist materials. By removing the hex bolt 10, the connector 10 can be removed, and the slide plate 8 will automatically rotate downwards to fit the surface of the ladder frame 1 and fold, thus reducing the space occupied when the device is not in use.

[0029] Compared with the prior art, the present invention has the following advantages: The safety ladder for bridge pier construction uses a hinge 7, a sliding plate 8, a baffle 9, and a connector 10. The connector 10's connecting mechanism, such as the use of hexagonal bolts, allows for the movement of a material discharge channel next to the ladder frame 1. Specifically, the sliding plate 8 and the baffle 9 are connected. When the sliding plate 8 is flush with the ladder frame 1, the connector 10 is installed using hexagonal bolts. The connector 10 connects the sliding plate 8 and the ladder frame 1, securing the sliding plate 8. Waste, scrap, and dismantled or replaced parts generated during bridge pier construction can slide down the sliding plate 8 to the ground, eliminating the need for workers to manually carry waste down, avoid the danger of throwing waste, or hoist materials. This reduces labor costs and improves the efficiency and speed of waste disposal.
