Technical Field

[0001] The utility model belongs to the technical field of tunnel construction, and more specifically relates to a hanging basket and an arch frame trolley. Background Art

[0002] In tunnel construction, arch rigs typically have several booms and several hanging baskets. If a rig has only two booms and two hanging baskets, construction workers work at the two hanging basket stations. This reduces construction efficiency by one-third compared to a rig with three booms and three hanging baskets.

[0003] In order to make the two-arm arch trolley achieve the effect of three hanging basket workstations, it is urgently needed to have a hanging basket that can expand both the width and the height in space to increase the construction workstations. Utility Model Content

[0005] Furthermore, the first expansion basket can be accommodated in the basic basket, and the first expansion basket is hinged to the basic basket; wherein the first expansion basket can be rotated relative to the basic basket to flip to the outside of the basic basket.

[0006] Furthermore, the bottom of the basic basket is provided with a hinge shaft 1, and the bottom of the first expansion basket is provided with a hinge shaft 2 that cooperates with the hinge shaft 1, and the hinge shaft 2 can rotate relative to the hinge shaft 1.

[0007] Furthermore, the basic basket is provided with a limiting plate 1, and the first expansion basket is provided with a limiting plate 2. When the first expansion basket is flipped to the outside of the basic basket, the limiting plate 1 cooperates with the limiting plate 2 to limit the flipping angle of the first expansion basket.

[0008] Furthermore, the basic basket includes two limiting plates 1, and the two limiting plates 1 are respectively arranged on both sides of the hinge shaft 1.

[0009] Furthermore, the hanging basket also includes: a lifting mechanism, which is telescopically arranged on one side of the basic basket and connected to the second expansion basket; wherein the lifting mechanism includes a fixed rod and at least one movable rod, and the movable rod is telescopically arranged inside the fixed rod.

[0010] Furthermore, the hanging basket also includes: a support rod, which is arranged at the top of the movable rod; a lifting basket mounting portion, which is arranged on the side of the support rod close to the second expansion basket; wherein the first expansion basket is mounted to the support rod through the lifting basket mounting portion.

[0011] Furthermore, there are two lifting mechanisms, and the support rod is connected between the two lifting mechanisms.

[0012] Furthermore, the lifting basket mounting part includes: a mounting seat, fixedly connected to the support rod; a mounting hole 1, arranged on the mounting seat; wherein, the second expansion basket is provided with a mounting hole 2 corresponding to the mounting hole 1, and the threaded mounting part can pass through the mounting hole 1 and the mounting hole 2 to fix the second expansion basket to the mounting seat.

[0013] Furthermore, the lifting basket mounting portion also includes: a positioning rod, which is arranged on the mounting seat and located above the mounting hole; wherein, the second expansion basket is provided with a corresponding positioning clip, and the positioning clip can be clamped on the positioning rod.

[0014] Furthermore, the present application provides an arch trolley, which uses any one of the hanging baskets described above and can achieve the same effect. To avoid repetition, it will not be described here.

[0015] Technical effects and advantages of this utility model:

[0016] 1. The hanging basket can be expanded in the horizontal direction through the first expansion basket, and can be expanded in the height direction through the second expansion basket, so that one hanging basket can have two workstations, and the two workstations have a distance in the width direction and a large height difference. The two workstations do not interfere with each other during construction, and the two-arm arch frame trolley can achieve the effect of three-arm three-basket workstations, thereby improving the construction efficiency of the two-arm arch frame trolley.

[0017] 2. Compared with the retractable structure, the first expansion basket is set to be flippable around the basic basket. There is no need to set tracks and pulleys between the first expansion basket and the basic basket. It is only necessary to hinge the first expansion basket with the basic basket, which is more convenient to operate and has a simpler structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0031] See also Figure 1 , which is a structural diagram of a hanging basket provided by the utility model. Figures 1 to 10The hanging basket, for example, includes a basic basket 10, a first expansion basket 20, and a second expansion basket 30. The first expansion basket 20 is movably mounted on the basic basket 10 to extend the horizontal working position of the hanging basket; the second expansion basket 30 is movably mounted on one side of the basic basket 10 to extend the vertical working position of the hanging basket.

[0032] The hanging basket can be expanded in the horizontal direction through the first expansion basket 20, and can be expanded in the height direction through the second expansion basket 30, so that one hanging basket can have two workstations, and the two workstations have a distance in the width direction and a large height difference. The two workstations do not interfere with each other during construction, and the two-arm arch frame trolley can achieve the effect of three-arm three-basket workstations, thereby improving the construction efficiency of the two-arm arch frame trolley.

[0033] Furthermore, the first expansion basket 20 can be housed within the basic basket 10 and hingedly connected to the basic basket 10, allowing the first expansion basket 20 to rotate relative to the basic basket 10. For example, when a hanging basket is used for construction work, the first expansion basket 20 housed within the basic basket 10 can rotate around the basic basket 10 and flip to the outside of the basic basket 10, allowing operators to perform tunnel construction work at the first expansion basket 20 outside the basic basket 10.

[0034] Compared with the retractable structure, the first expansion basket 20 is configured to be flippable around the basic basket 10. There is no need to set tracks and pulleys between the first expansion basket 20 and the basic basket 10. It is only necessary to hinge the first expansion basket 20 to the basic basket 10, which is more convenient to operate and has a simpler structure.

[0035] Furthermore, a hinge axis 1 41 is provided at the bottom of the base basket 10, and a hinge axis 2 42 is provided at the bottom of the first expansion basket 20 to cooperate with hinge axis 1 41. Hinge axis 2 42 is capable of rotating relative to hinge axis 1 41. When the first expansion basket 20 flips around the base basket 10, hinge axis 2 42 rotates relative to hinge axis 1 41.

[0036] Furthermore, the basic basket 10 is provided with a limiting plate 1 51 , and the first expansion basket 20 is provided with a limiting plate 2 52 . When the first expansion basket 20 is flipped to the outside of the basic basket 10 , the limiting plate 1 51 cooperates with the limiting plate 2 52 to limit the flipping angle of the first expansion basket 20 .

[0037] For example, when the first expansion basket 20 is flipped to the target position, the second limit plate 52 is located on the inner side of the first limit plate 51, and the first limit plate 51 and the second limit plate 52 are in surface contact, preventing the first expansion basket 20 from further flipping, thereby limiting the flipping angle of the first expansion basket 20.

[0038] In a specific embodiment, the first expansion basket 20 accommodated in the basic basket 10 is rotated 180 degrees relative to the basic basket 10 via the second hinge shaft 42 and flipped to the target position. At this time, the second limit plate 52 is located on the side of the first limit plate 51 facing the inside of the basic basket 10, and the first limit plate 51 and the second limit plate 52 are in surface contact, thereby preventing the first expansion basket 20 from further flipping.

[0039] Furthermore, the base basket 10 is provided with two first-limiting plates 51, each located on either side of the first hinge axis 41. For example, the width of the first expansion basket 20 is smaller than that of the base basket 10, and the first hinge axis 41 is provided in the width direction of the base basket 10. An opening is provided above the first hinge axis 41, and the two first-limiting plates 51 are provided on either side of the opening along the height direction of the base basket 10. Correspondingly, the first expansion basket 20 is provided with two second-limiting plates 52, and the sum of the width of the two second-limiting plates 52 plus the width of the first expansion basket 20 is greater than the width of the opening minus the width of the two first-limiting plates 51.

[0040] By providing two limiting plates 51 on the basic basket 10 , the first expansion basket 20 can be better limited after the first expansion basket 20 is flipped into place, thereby improving the connection reliability between the basic basket 10 and the first expansion basket 20 .

[0041] For example, L-shaped bent plates are provided on both sides of the opening. The L-shaped bent plates include a mounting plate and a limiting plate 51. The L-shaped bent plates are fixedly connected to the base basket 10 via the mounting plate, and the limiting plate 51 is used to limit the rotation of the first expansion basket 20. For example, the mounting plate is connected to the limiting plate 51 in an arc shape.

[0042] Furthermore, the hanging basket includes a lifting mechanism 60. The lifting mechanism 60 is telescopically disposed on one side of the base basket 10 and is connected to the second expansion basket 30. The second expansion basket 30 is lifted and lowered on one side of the base basket 10 via the lifting mechanism 60. For example, the lifting mechanism 60 and the first expansion basket 20 are disposed on opposite sides of the base basket 10.

[0043] The lifting mechanism 60 includes a fixed rod 61 and at least one movable rod 62. The fixed rod 61 is sleeved on the outside of the movable rod 62. The movable rod 62 can slide inside the fixed rod 61 to achieve the extension and retraction of the lifting mechanism 60. The number of sections of the movable rod 62 can be adjusted according to specific needs, and there is no limitation here. For example, the fixed rod 61 and the movable rod 62 are square tubes. In a specific embodiment, the lifting mechanism 60 includes one fixed rod 61 and two movable rods 62. The bottom of the fixed rod 61 is fixedly connected to the bottom plate of the basic basket 10, and triangular reinforcing ribs are provided around the side of the fixed rod 61; a clamp is also provided between the fixed rod 61 and the side railing of the basic basket 10.

[0044] Furthermore, the hanging basket includes a support rod 63 and a basket mounting portion 70. The support rod 63 is mounted on top of the movable rod 62; the basket mounting portion 70 is located on the side of the support rod 63 near the second expansion basket 30. The second expansion basket 30 is mounted to the support rod 63 at the top of the lifting mechanism 60 via the basket mounting portion 70. For example, the hanging basket can be equipped with a lifting mechanism 60, with the support rod 63 disposed at the top of the lifting mechanism 60 in a T-shaped configuration.

[0045] In one embodiment, there are two lifting mechanisms 60, with a support rod 63 connected between the two lifting mechanisms 60. Specifically, the two lifting mechanisms 60 are arranged in parallel, with the support rod 63 connected to the top ends of the two movable rods 62. Compared to a T-shaped structure, the provision of two lifting mechanisms 60 can better support the lifting basket mounting portion 70 and the second expansion basket 30, ensuring smooth lifting of the second expansion basket 30.

[0046] Furthermore, the basket mounting portion 70 includes, for example, a mounting seat 71 and a first mounting hole 72. The mounting seat 71 is fixedly connected to the side of the support rod 63 near the second expansion basket 30, and the first mounting hole 72 is defined in the mounting seat 71. The second expansion basket 30 is provided with a second mounting hole 81 corresponding to the first mounting hole 72. A threaded connector can pass through the first mounting hole 72 and the second mounting hole 81 to securely mount the second expansion basket 30 to the mounting seat 71.

[0047] Furthermore, the lifting basket mounting portion 70 further includes, for example, a positioning rod 73. The positioning rod 73 is provided on the mounting seat 71 and is located above the mounting hole 1 72. The second expansion basket 30 is provided with a corresponding positioning clip 32, and the positioning clip 32 can be clamped on the positioning rod positioning rod 73. For example, the positioning clip 32 is provided with a positioning slot, or the positioning clip 32 is in the shape of a hook. When the positioning clip 32 is clamped on the positioning rod positioning rod 73, the mounting hole 1 72 is aligned with the mounting hole 2 81. For example, there are two mounting seats 71, and each mounting seat 71 is provided with a mounting hole 1 72. The positioning rod 73 is connected between the two mounting seats 71; when the positioning clip 32 is clamped on the positioning rod 73, the two positioning clips 32 are clamped between the two mounting seats 71.

[0048] It can be understood that by providing a positioning clip 32 on the second expansion basket 30 and providing a positioning rod 73 on the lifting basket mounting portion 70, when the positioning clip 32 is clamped on the positioning rod 73, the mounting hole 1 72 and the mounting hole 2 81 can be pre-positioned, thereby improving the installation efficiency of the second expansion basket 30.

[0049] Furthermore, the present application provides an arch trolley, which uses any of the above-mentioned hanging baskets and can achieve the same effect. To avoid repetition, it is not described here. In a specific embodiment, the arch trolley is provided with two arms.
