[0019] like Figure 1 , Figure 2 as well as Figure 3 As shown, the utility model is a multifunctional construction engineering ladder, and its structure mainly includes a first ladder unit 1 and a second ladder unit 2 which are hinged to each other, wherein the structures of the first ladder unit 1 and the second ladder unit 2 are basically the same, both of which include support rods 3 on both sides and a plurality of parallel adjustment beams 4 located between the support rods 3 on both sides, the two support rods 3 are parallel to each other, the adjustment beams 4 are perpendicular to the support rods 3, and the plurality of adjustment beams 4 are evenly distributed along the length direction of the support rods 3. At the same time, a plurality of rollers 5 are arranged on the support rods 3, the axial direction of the rollers 5 is consistent with the length direction of the adjustment beams 4, and the plurality of rollers 5 are evenly distributed along the length direction of the support rods 3. In addition, adjustable supports 6 are respectively hingedly arranged on the first ladder unit 1 and the second ladder unit 2, and the adjustable supports 6 include two adjustable legs 6-1 and an adjustable clamping plate 6-2 located between the two adjustable legs 6-1.

[0020] The overall width of the utility model can be adjusted to meet the different requirements of ladder width in different occasions or different work needs. The width of the utility model is adjusted by adjusting the crossbeam 4, which includes a supporting crossbeam 4-1 and a telescopic crossbeam 4-2 located at both ends of the supporting crossbeam 4-1. The supporting crossbeam 4-1 and the telescopic crossbeam 4-2 are sleeved. The overall width of the utility model can be adjusted by adjusting the length of the two telescopic crossbeams 4-2. A plurality of bolt holes 13 are provided on the supporting crossbeam 4-1 and the telescopic crossbeam 4-2. After adjusting to a predetermined width, the bolts are passed through the bolt holes 13 to fix the sleeved supporting crossbeam 4-1 and the telescopic crossbeam 4-2 together, thereby fixing the width of the ladder. The ends of the telescopic crossbeams 4-2 on both sides are connected to the support rod 3, and the telescopic crossbeam 4-2 and the support rod 3 are an integral structure, and all the supporting crossbeams 4-1 on the first ladder unit 1 / the second ladder unit 2 are connected by the supporting vertical beam 12, and the supporting crossbeam 4-1 and the supporting vertical beam 12 are an integral structure.

[0021] Among them, the support rod 3, the telescopic beam 4-2, the supporting beam 4-1 and the supporting vertical beam 12 are all square tube structures.

[0022] Since the first ladder unit 1 and the second ladder unit 2 are hingedly connected, the first ladder unit 1 and the second ladder unit 2 can be adjusted to different opening angles. In this embodiment, the first ladder unit 1 and the second ladder unit 2 can be adjusted to a "herringbone" or "straight" structure.

[0023] A connecting piece 7 is provided at the end of the supporting rod 3 , and the connecting piece 7 on the first ladder unit 1 and the connecting piece 7 on the second ladder unit 2 form a hinge structure through a pin shaft 8 .

[0024] like Figure 1 , 2 As shown, when the structure is in a "herringbone" shape, the function of the utility model is mainly used for climbing operations, wherein the adjustable crossbeam 4 is used as a step of the ladder for the operator to step on, and the support rods 3 on both sides support the entire ladder and are provided for the operator to hold on. In this state, the adjustable supports 6 on the first ladder unit 1 and the second ladder unit 2 are folded inside the ladder and abut against the inner side surface of the first ladder unit 1 or the second ladder unit 2 to avoid affecting the normal use of the ladder.

[0025] In order to ensure the stability of the "herringbone" ladder when in use, angle control rods 9 are hinged on the first ladder unit 1 and the second ladder unit 2, respectively, and the angle control rods 9 are specifically hinged on the support rods 3. When the first ladder unit 1 and the second ladder unit 2 of the utility model form a "herringbone" structure, the angle control rods 9 on the first ladder unit 1 and the angle control rods 9 on the second ladder unit 2 are connected to each other to form a stable triangular structure, thereby limiting the opening angle of the first ladder unit 1 and the second ladder unit 2. The angle control rods 9 on the first ladder unit 1 and the angle control rods 9 on the second ladder unit 2 can be connected in a snap-fit ​​connection, overlapped connection or other connection forms, as long as a stable connection between the two can be achieved.

[0026] In order to further ensure the stability of the “herringbone” ladder when in use, an anti-slip pad 10 is provided at the lower end of the support rod 3 .

[0027] like Figure 3As shown, when it is a "straight" structure, the function of the utility model is mainly used to transport materials. The first ladder unit 1 and the second ladder unit 2 are connected to each other to form a transport plane. The roller 5 is located on the upper surface of the transport plane. The material can move quickly along the transport plane through the roller 5 to achieve rapid transportation of the material. The transport plane is generally an inclined plane, so that it is convenient to directly transport the material at two different height planes. At this time, the utility model is supported by an adjustable support 6, and the adjustable support 6 is unfolded to a vertical state. The inclination angle of the transport plane is adjusted by the height of the two adjustable supports 6.

[0028] The adjustable leg 6-1 includes a support fixing member 6-3, a support top tube 6-4, a support middle tube 6-5 and a support bottom tube 6-6. The support fixing member 6-3 is fixed on the support rod 3, and is generally fixed to the middle and upper part of the support rod 3. The support top tube 6-4 is hinged to the support fixing member 6-3. The upper end of the support middle tube 6-5 is sleeved on the support top tube 6-4. The lower end of the support middle tube 6-5 is sleeved on the support bottom tube 6-6. The length of the adjustable leg 6-1 is adjusted by adjusting the telescopic length of the support top tube 6-4, the support middle tube 6-5 and the support bottom tube 6-6. A plurality of bolt holes 13 are distributed on the support top tube 6-4, the support middle tube 6-5 and the support bottom tube 6-6, and the support top tube 6-4 and the support middle tube 6-5, and the support bottom tube 6-6 and the support middle tube 6-5 are fixed by bolts, thereby fixing the length of the adjustable leg 6-1.

[0029] The support top tube 6-4, the support middle tube 6-5 and the support bottom tube 6-6 are all square tube structures.

[0030] The adjustable clamping plate 6-2 includes two rods with long holes, and bolts pass through the long holes of the two rods at the same time, and the two rods are fixed by the bolts. The ends of the adjustable clamping plate 6-2 are fixed to the bottom tube 6-6 of the support by pins. When the width of the utility model is adjusted, the length of the adjustable clamping plate 6-2 between the two adjustable legs 6-1 in the support 6 can be adjusted at the same time.

[0031] The four adjustable legs 6-1 are supported on the ground. In addition to setting an adjustable splint 6-2 between the two adjustable legs 6-1 of the same adjustable support 6, an additional adjustable splint 6-2 is required between the adjustable legs 6-1 of the two adjustable supports 6 to ensure the overall stability of the utility model.

[0032] An anti-skid pad 10 is provided at the lower end of the adjustable leg 6-1, that is, the lower end of the supporting bottom tube 6-6, to further improve the stability of the utility model.

[0033] In addition, a clamping plate 11 is provided at the end of the first ladder unit 1 or the second ladder unit 2. In the present embodiment, the clamping plate 11 is provided at the ends of the two support rods 3 of the first ladder unit 1. The clamping plate 11 is an L-shaped structure, and the corners of the clamping plate 11 are hinged to the surfaces of the support rods 3.

[0034] When in use, the first ladder unit 1 is tilted upward, and the clamping plate 11 can overlap on a higher plane to prevent the ladder from moving during material transportation.

[0035] The two side panels of the L-shaped card plate 11 are perpendicular to each other, and the side panel close to the end of the support rod 3 is shorter than the other side panel. When the card plate 11 is not needed to overlap, the card plate 11 is rotated to make the longer side panel fit against the surface of the support rod 3, and the shorter side panel is extended without affecting the normal use of the ladder. When the card plate 11 is needed to overlap, the card plate 11 is rotated to make the shorter side panel fit against the surface of the support rod 3, and the longer side panel is extended and the longer side panel is limited by the shorter side panel so that it is perpendicular to the surface of the support plate.

[0036] The utility model is composed of a first ladder unit 1 and a second ladder unit 2. The width of the first ladder unit 1 and the second ladder unit 2 can be adjusted by adjusting the crossbeam 4. The first ladder unit 1 and the second ladder unit 2 are hinged to each other. The first ladder unit 1 and the second ladder unit 2 can form two states, "herringbone" and "straight". When in the "herringbone" state, the utility model is used for high-altitude operations. When in the "straight" state, the first ladder unit 1 and the second ladder unit 2 are located on the same plane, and the adjustable support 6 is lowered and supported on the ground or the surface of the building structure. The roller 5 can be used to transport building materials, and the inclination angle of the first ladder unit 1 and the second ladder unit 2 can be adjusted, so as to realize material transportation at different angles. The utility model can adjust the width and change the shape to have different functions, improve work efficiency, and realize the multifunctional use of the ladder.
