[0002] In the field of construction technology, currently, for high-rise buildings, vertical cranes and truck cranes are used for material transportation on construction sites. However, for low-rise buildings, due to their shorter height, while using large lifting equipment such as tower cranes and truck cranes can improve transportation efficiency, the rental, installation, and dismantling costs are high, hindering cost control. Manual material transportation, although avoiding equipment costs, requires significant manpower and time, resulting in low efficiency and increasing worker fatigue and safety risks. Therefore, there is an urgent need for a simple, easy-to-assemble and disassemble low-rise transportation device. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, the technical problem to be solved by this utility model is to propose a low-level transportation device, which adopts the following technical solution:
[0004] A low-level transport device, comprising
[0005] The first parallel guide rail is used for vertical transport, with one end fixed to the ground and the other end hinged to the second parallel guide rail, which is used for horizontal transport.
[0006] The transport trolley includes a cargo support frame, a guide rail support hinged in the middle of the cargo support frame, a guide member slidably connected to the first parallel guide rail and the second parallel guide rail on the guide rail support frame, and the guide member is provided on the side of the cargo support frame away from the guide rail support frame.
[0007] The traction motor is connected to the aforementioned transport trolley via a traction rope.
[0008] As a further improvement, the guide rail bracket is disposed on the lower side of the cargo support, the upper end of the cargo support is provided with the guide member, and the lower end of the guide rail bracket is provided with the guide member. When the transport trolley slides from the first parallel guide rail to the second parallel guide rail, the cargo support is parallel to the second parallel guide rail, and the guide rail bracket is parallel to the first parallel guide rail.
[0009] As a further improvement, the lower end of the aforementioned cargo support is provided with a limiting plate that abuts against the upper surface of the aforementioned guide rail support.
[0010] As a further improvement, the above-mentioned support frame is equipped with columns at both the top and bottom to prevent materials from falling.
[0011] As a further improvement, the guide includes a support member, and two rollers are vertically arranged on the inner side of the support member. The two rollers respectively abut against the upper and lower end faces of the first or second parallel guide rail.
[0012] As a further improvement, a crossbar is provided at the upper end of the first parallel guide rail or the lower end of the second parallel guide rail, and a guide member is provided on the crossbar, with the traction rope resting on the guide member.

[0016] As a further improvement, both the first and second parallel guide rails are equipped with support frames for supporting the wall or the ground.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] A transport track is formed by a first parallel guide rail and a second parallel guide rail that are hinged together. The first parallel guide rail is used for longitudinal transport of materials, and the second parallel guide rail is used for lateral transport of materials. A transport trolley is set on the first and second parallel guide rails for longitudinal and lateral transport of materials at lower levels. Specifically, the transport trolley includes a load-bearing bracket and a guide rail bracket that are hinged together, both connected to the first or second parallel guide rail via guide components. When the transport trolley moves from the first parallel guide rail to the second parallel guide rail, the load-bearing bracket and the guide rail bracket open at a certain angle, allowing the load-bearing bracket and the guide rail bracket to switch sequentially to the second parallel guide rail. During this process, the load-bearing bracket is lifted first, allowing the materials to be transported smoothly. This utility model has a simple overall structure, which can save the cost of using large lifting equipment or manual transport of materials. Compared with large lifting equipment, it is simpler, more practical, and more cost-effective. It can be modified or repositioned according to the actual site conditions, and is more convenient, efficient, and cost-effective than traditional manual transport of materials, thereby accelerating the construction period.

[0029] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0031] like Figures 1-2As shown, this application provides a low-level transport device, including a first parallel guide rail 1 and a second parallel guide rail 2. The first parallel guide rail 1 is used for vertical transport, with one end fixed to the ground and the other end hinged to the second parallel guide rail 2, which is used for horizontal transport. It also includes a transport trolley 3, which includes a load support 31. A guide rail support 32 is hinged to the middle of the load support 31. A guide member 33 is provided on the guide rail support 32, which is slidably connected to the first parallel guide rail 1 and the second parallel guide rail 2. The guide member 33 is located on the side of the load support 31 away from the guide rail support 32. The transport trolley 3 is connected to a traction motor 4 via a traction rope 41. Driving the traction motor 4 pulls the transport trolley 3 from the first parallel guide rail 1 to the second parallel guide rail 2, thus realizing both vertical and horizontal transport of materials from the ground to the lower level.
[0032] In one specific embodiment, both the first parallel guide rail 1 and the second parallel guide rail 2 are square frames with parallel guide rails on both sides. The lower end of the first parallel guide rail 1 abuts against the first level, and the upper end is provided with a hinge, which is hinged to the second parallel guide rail 2. The hinge is located on the end face, allowing the transport trolley 3 to slide smoothly from the first parallel guide rail 1 to the second parallel guide rail 2. The upper end face of the second parallel guide rail 2 is mounted on the second level. In actual construction, the connection surfaces between the first and second levels are not necessarily square. By using the hinged first parallel guide rail 1 and the second parallel guide rail 2, it can be applied to various low-level handling scenarios. The above structure is simple, can be quickly assembled in the construction scene, and can be quickly disassembled and stored or transported to other locations after construction, showing significant convenience and versatility.
[0033] like Figures 1-2 As shown, the guide rail bracket 32 of the transport trolley 3 is disposed on the lower side of the cargo support 31. A guide member 33 is disposed at the upper end of the cargo support 31, and a guide member 33 is also disposed at the lower end of the guide rail bracket 32. In this embodiment, as... Figure 2 As shown, when the transport trolley 3 slides from the first parallel guide rail 1 to the second parallel guide rail 2, the load support 31 is parallel to the second parallel guide rail 2, and the guide rail support 32 is parallel to the first parallel guide rail 1. At this time, the rear end of the load support 31 is tilted up, so the material will not fall off, and the guide rail support 32 slides on the first parallel guide rail 1 to ensure the stability of the trolley.
[0034] Specifically, the guide rail bracket 32 and the load bracket 31 are square frames. The lower end of the load bracket 31 is provided with a limiting plate 34 that abuts against the upper surface of the guide rail bracket 32. During loading, the material is placed on the load bracket 31 and secured to the frame of the load bracket 31 with ropes or wrapped cloth. The limiting plate 34 ensures that the load bracket 31 is normally positioned above the guide rail bracket 32, facilitating material placement and securing. Preferably, the upper and lower ends of the load bracket 31 are provided with uprights 35 to prevent material from falling. For the first and second levels with large slopes, the uprights 35 are sufficient to prevent material from falling. For the first and second levels with large slopes, ropes for securing the material can be further wrapped around the uprights 35 to secure the material. The structure is simple, easy to operate, and highly flexible.
[0035] like Figure 3 As shown, in one specific embodiment, the guide 33 includes a support 331. Two rollers 332 are vertically arranged on the inner side of the support 331, and the two rollers 332 respectively abut against the upper and lower ends of the first parallel guide rail 1 or the second parallel guide rail 2. Preferably, the diameter of the rollers 332 is larger than the width of the hinge between the first parallel guide rail 1 and the second parallel guide rail 2, to prevent the transport trolley 3 from sinking when passing through the hinge area, thus avoiding uneven sliding. Furthermore, the guide wheels on the left and right sides are arranged one in front of the other. During transport, the rollers 332 on the left and right sides pass through the hinge area one in front of the other, preventing both rollers 332 from sinking simultaneously, thus avoiding uneven transport.
[0036] like Figure 1 and Figure 3 As shown, a crossbar 11 is provided at the upper end of the first parallel guide rail 1 or the lower end of the second parallel guide rail 2. A guide member 111 is provided on the crossbar 11, and a traction rope 41 is attached to the guide member 111. Specifically, the motor is located at the lower end of the first parallel guide rail 1, a first guide wheel 112 is provided at the bottom of the crossbar 11, and a second guide wheel 21 is provided at the upper end of the second parallel guide rail 2. The traction rope 41 runs from the lower side of the first parallel guide rail 1, passes through the first guide wheel 112 and the second guide wheel 21, and then winds around to the upper side of the second parallel guide rail 2, before connecting to the load support 31 via the guide member 111. More specifically, a lower limit bar 13 is provided at the lower side of the first parallel guide rail 1, and an upper limit bar 22 is provided at the upper side of the second parallel guide rail 2. The transport trolley 3 slides between the upper limit bar 22 and the lower limit bar 13. The motor can be installed below the lower limit bar 13 or above the upper limit bar 22.
[0037] In another embodiment, the motor is located at the upper end of the second parallel guide rail 2, and the traction rope 41 is connected to the load support 31 from the upper side of the second parallel guide rail 2 via the second guide wheel 21 and the guide member 111. The user can install it according to the needs.
[0038] like Figure 3As shown, to enhance structural strength, several horizontal support rods 12 are respectively installed between the first parallel guide rail 1 and the second parallel guide rail 2. Both the first parallel guide rail 1 and the second parallel guide rail 2 are equipped with support frames 5 for supporting the wall or floor. However, it should be noted that the connection position of the support frame 5 should be inside the first parallel guide rail 1 and the second parallel guide rail 2. If it is located on the lower end face, care should be taken to reserve a sliding position for the guide member 33, specifically as follows... Figure 3 As shown.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
