Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a material transport device for the construction of urban overpasses. Background Technology

[0002] Vertical transportation of building materials is a crucial aspect of urban overpass construction. Traditional methods typically rely on scaffolding, tower cranes, or manual labor, but these methods have significant limitations. Scaffolding is time-consuming and costly to erect, tower cranes have limited coverage and are unsuitable for small or dispersed construction areas, while manual labor is not only inefficient but also poses high safety risks.

[0003] In the existing technology, some construction sites still use simple hoisting devices (such as a combination of pulleys, ropes and material boxes) to transport materials. However, these devices lack effective limiting structures during the lifting process, which makes the material boxes easy to shake, or even tilt or fall, threatening the safety of construction workers. Utility Model Content

[0004] The purpose of this invention is to provide a material transport device for the construction of urban overpasses, thereby addressing the shortcomings in the aforementioned background technology.

[0005] The technical solution of this utility model is: a material transport device for the construction of urban overpasses, comprising: a frame, a material box, and a lifting mechanism. The lifting mechanism is mounted on the frame and includes a lifting drive assembly for lifting the material box and a lifting guide assembly for guiding the lifting process of the material box. The material box includes an inner box and an outer box, which are connected to the outer box via a lateral drive assembly and a lateral guide assembly. The lateral drive assembly drives the inner box to move laterally inside and outside the outer box, and the lateral guide assembly guides the lateral movement of the inner box.

[0006] Preferably, the lifting drive assembly includes a winch, a first lifting rope, and a second lifting rope. Several groups of the second lifting rope are distributed around the outer casing. The several groups of the second lifting rope are gathered by a connector at the bottom end of the first lifting rope and connected to the winch through the first lifting rope.

[0007] Preferably, the lifting guide assembly includes a guide post and a guide sleeve. The guide post extends along the height of the frame and is distributed in several groups around the outer casing. The guide sleeve is sleeved on the guide post and its outer wall is fixedly connected to the outer casing.

[0008] Preferably, the outer casing has an open sidewall, and the lateral movement drive assembly includes:

[0009] A sliding block, through which the inner box is slidably connected to the outer box;

[0010] A drive screw, perpendicular to the sidewall of the opening, passes through and is threaded to the slide block;

[0011] A drive motor is mounted on the outer casing and is used to drive the transmission screw to rotate.

[0012] Preferably, the transverse guide assembly includes several sets of guide rods perpendicular to the sidewall of the opening, and the outer box is provided with a guide groove extending in the same direction as the guide rod. One end of the guide rod slides through the guide groove, and the other end is connected to the inner box through a connecting block.

[0013] Preferably, the side wall of the inner box is provided with a hinged door panel, and adjacent hinged door panels are connected by a snap fastener.

[0014] Preferably, the outer casing is provided with a limiting groove extending in the same direction as the guide groove, and the long end of the limiting groove is spaced from the opening sidewall; the inner casing is connected to a limiting block that is slidably disposed in the limiting groove.

[0015] Preferably, the bottom of the frame is provided with casters and fixed feet. The fixed feet include a mounting plate, a foot screw, and a foot base plate. The foot screw extends along the height of the frame, passes through and is threaded to the mounting plate. The foot base plate is located at the bottom of the foot screw.

[0016] Preferably, the frame includes a top plate and several columns. The top plate is located at the top of the columns and is used to install the lifting drive assembly. The columns are used to install the lifting guide assembly, and their outer walls are provided with scale markings that are distributed along their height.

[0017] The beneficial effects of this utility model are as follows: the lifting drive component improves the lifting efficiency of the material box, and the lifting guide component improves the stability of the material box during the lifting process, which can reduce the safety risks of operation. When the material box reaches the designated height, the lateral drive component moves the inner box out of the outer box, so that part of the weight of the inner box falls on the scaffolding or other structures, preventing the material box from falling out of the box during the unloading process of workers, further reducing the safety risks of operation; in addition, the lateral guide component can improve the smoothness of the lateral movement of the inner box, making the use and operation of the material box smoother and more convenient.

[0034] Reference Appendix Figure 1-3This embodiment provides a material transport device for the construction of urban overpasses, comprising: a frame 1, a material box 2, and a lifting mechanism. The lifting mechanism is mounted on the frame 1 and includes a lifting drive assembly 3 for lifting the material box 2 and a lifting guide assembly 4 for guiding the lifting process of the material box 2. The material box 2 includes an inner box 2.1 and an outer box 2.2. The outer box 2.2 has an open sidewall 2.3. The inner box 2.1 and the outer box 2.2 are connected by a transverse drive assembly 5 and a transverse guide assembly 6. The transverse drive assembly 5 drives the inner box 2.1 to move laterally into and out of the outer box 2.2 at the open sidewall 2.3 of the outer box 2.2. The transverse guide assembly 6 guides the transverse movement of the inner box 2.1.

[0035] By adopting the above technical solution, the lifting efficiency of the material box 2 is improved by the lifting drive component 3, and the stability of the material box 2 during the lifting process is improved by the lifting guide component 4, which can reduce the safety risks of the operation. When the material box 2 reaches the designated height, the inner box 2.1 is moved out of the outer box 2.2 by the lateral movement drive component 5, so that part of the weight of the inner box 2.1 falls on the scaffolding and other structures, preventing the material box 2 from falling during the unloading process of the workers, and further reducing the safety risks of the operation. In addition, the lateral movement guide component 6 can improve the smoothness of the lateral movement of the inner box 2.1, making the use and operation of the material box 2 smoother and more convenient.

[0036] Reference Appendix Figure 2 In this embodiment, the frame 1 includes a top plate 1.1 and four columns 1.2. The top plate 1.1 is located at the top of the columns 1.2 and is used to install the lifting drive assembly 3. The four columns 1.2 are arranged in a ring around the outer periphery of the material box 2 and are used to install the lifting guide assembly 4. The outer wall of the columns 1.2 is provided with scale markings that are distributed along their own height to mark the lifting height of the material box 2, so that workers can easily check and judge the lifting height of the material box 2.

[0037] The lifting drive assembly 3 includes a winch 3.1, a first lifting rope 3.2, and a second lifting rope 3.3. Four sets of the second lifting ropes 3.3 are distributed circumferentially around the outer casing 2.2 and connected to the outer casing 2.2 via lifting rings 2.4 located on the outer casing 2.2. The tops of the four sets of second lifting ropes 3.3 are gathered by connectors 3.4 at the bottom of the first lifting ropes 3.2, and connected to the winch 3.1 via the first lifting ropes 3.2. The connectors 3.4 can be configured into any suitable shape, such as a block structure with lifting points on both the top and bottom surfaces. The lifting points on the top surface are used to connect to the first lifting rope 3.2, and the lifting points on the bottom surface are used to connect to the second lifting ropes 3.3. When materials need to be transported, the winch 3.1 is started to wind up or lower the first lifting rope 3.2, which in turn drives the material box 2 to rise and fall via the second lifting ropes 3.3.

[0038] The lifting guide assembly 4 includes four guide posts 4.1 and four guide sleeves 4.2. The guide posts 4.1 extend along the height of the frame 1, that is, they extend in the same direction as the uprights 1.2 of the frame 1. The four guide posts 4.1 are distributed in a ring around the outer periphery of the material box 2 and are fixedly connected to the uprights 1.2 of the frame 1. The guide sleeves 4.2 are sleeved on the guide posts 4.1 and their outer walls are fixedly connected to the outer box 2.2.

[0039] When the winch 3.1 starts, the material box 2 will move along the height of the column 1.2 under the action of the second lifting rope 3.3 of the first lifting rope 3.2. The outer box 2.2 of the material box 2 is connected to the guide sleeve 4.2. Since the guide sleeve 4.2 is restricted by the guide column 1.2, it can only slide along the extension direction of the guide column 1.2. Thus, the outer box 2.2 of the material box 2 can be guided or limited in many places by the guide sleeve 4.2 and the guide column 1.2, which can ensure the stability of its lifting process and avoid tilting and material falling, which could cause safety accidents.

[0040] Reference Appendix Figure 3 The transverse drive assembly 5 includes a slide 5.1, a transmission screw 5.2, and a drive motor 5.3. The inner box 2.1 is slidably connected to the outer box 2.2 through the slide 5.1. The transmission screw 5.2 is perpendicular to the opening side wall 2.3 of the outer box 2.2, passes through and is threaded to the slide 5.1. The drive motor 5.3 is mounted on the outer box 2.2 and is used to drive the transmission screw 5.2 to rotate.

[0041] Since the transmission screw 5.2 is perpendicular to the opening side wall 2.3 of the outer box 2.2, when it is driven by the drive motor 5.3 to rotate, the slide 5.1 can move along its axial direction, thereby driving the inner box 2.1 to enter and exit the outer box 2.2 from the opening side wall 2.3.

[0042] It is worth noting that, in order to avoid the slide 5.1 rotating and affecting the smooth lateral movement of the inner box 2.1, the slide 5.1 and the outer box 2.2 should only have sliding freedom and not rotational freedom. For example, a rectangular groove 2.5 can be dug inside the outer box 2.2, and the outer contour of the slide 5.1 can be set to a rectangular cross-section, so that when the slide 5.1 is subjected to the force from the transmission screw 5.2, it can only move along its axial direction and cannot rotate around it.

[0043] In practice, the transmission screw 5.2 can be rotatably mounted on the long end of the slide groove 2.5 via a bearing, and the drive motor 5.3 and the transmission screw 5.2 can be connected via a coupling.

[0044] The transverse guide assembly 6 includes two sets of guide rods 6.1 perpendicular to the upper opening sidewall 2.3 of the outer box 2.2. The outer box 2.2 is provided with a guide groove 6.2 extending in the same direction as the guide rods 6.1. One end of the guide rod 6.1 slides through the guide groove 6.2, and the other end is connected to the inner box 2.1 through the connecting block 6.3.

[0045] The guide rod 6.1 is connected to the connecting block 6.3 to form a T-shaped structure, that is, the outer wall of the guide rod 6.1 and the outer wall of the inner box 2.1 have a certain distance to avoid affecting the sliding of the guide rod 6.1 in the guide groove 6.2.

[0046] The long ends of the aforementioned chute 2.5 and guide groove 6.2 can extend to the opening sidewall 2.3. To prevent the inner box 2.1 from slipping out of the outer box 2.2, this embodiment also provides a limiting groove 7 extending in the same direction as the guide groove 6.2 on the outer box 2.2. The long end of the limiting groove 7 is spaced from the opening sidewall 2.3. The inner box 2.1 is connected to a limiting block 8 that is slidably disposed in the limiting groove 7. During the transverse movement of the material box 2, the limiting block 8 can also slide in the limiting groove 7. However, since the long end of the limiting groove 7 does not extend to the opening sidewall 2.3, the inner box 2.1 can be prevented from slipping out of the outer box 2.2.

[0047] To facilitate loading and unloading, this embodiment features an opening on the side of the inner box 2.1 and a hinged door panel 2.6, with adjacent hinged door panels 2.6 connected by snap-fit ​​fasteners. When loading and unloading is required, the hinged door panel 2.6 can be opened, allowing workers to easily load and unload materials from the side.

[0048] Furthermore, in this embodiment, the bottom of the frame 1 is provided with casters 9 and fixed feet 10. The fixed feet 10 include a mounting plate 10.1, a foot screw 10.2, and a foot base plate 10.3. The foot screw 10.2 extends along the height of the frame 1, passes through and is threaded to the mounting plate 10.1. The foot base plate 10.3 is located at the bottom of the foot screw 10.2. The arrangement of the casters 9 allows the device to be moved to a designated position as needed. When the device is moved to the designated position, the foot base plate can be lowered by screwing the foot screw 10.2. 10.3 The base plate 10.3 is used to increase the contact area with the ground, thereby improving the stability of the support. The verticality of the guide column 4.1 in this device can be corrected by adjusting the lowering height of different base plates 10.3 (determined by observing the horizontality of the surface perpendicular to the guide column 4.1. For example, if the mounting plate 10.1 is welded and fixed perpendicular to the guide column 4.1, the horizontality of the mounting plate 10.1 can be observed by observing the level bubble, etc., to determine the verticality of the guide column 4.1). This ensures the smoothness and stability of the lifting of the material box 2 and avoids tilting.

[0049] To facilitate the tightening of the support screw 10.2, a tightening handle 10.4, a tightening disc, or other components can be installed at the top of the support screw 10.2.

[0050] When using this device to transport materials:

[0051] Push the frame 1 to move it to the designated position, tighten the support screws 10.2 and lower the support base plate 10.3 to make the frame 1 stably supported and prevent it from shifting during material transportation;

[0052] Load material into material box 2, start winch 3.1 to wind up first lifting rope 3.2, and move material box 2 to the designated height through first lifting rope 3.2 and second lifting rope 3.3;

[0053] Start the drive motor 5.3 to move the inner box 2.1 out laterally from the opening side wall 2.3 of the outer box 2.2, and partially place it on the scaffolding;

[0054] The worker opened the hinged door panel 2.6 to unload the material.

[0055] In practice, a programmable controller (existing technology, not described in detail) can be installed on the top plate 1.1, and the drive motor 5.3 and winch 3.1 can be controlled by wireless remote control, making operation more convenient.

[0056] Compared with the prior art, the present invention has at least the following beneficial effects: the lifting drive component 3 improves the lifting efficiency of the material box 2, and the lifting guide component 4 improves the stability of the material box 2 during the lifting process, which can reduce the safety risks of operation. When the material box 2 reaches the designated height, the lateral drive component 5 moves the inner box 2.1 out of the outer box 2.2, so that part of the weight of the inner box 2.1 falls on the scaffolding or other structures, preventing the material box 2 from falling during the unloading process of the workers, and further reducing the safety risks of operation; in addition, the lateral guide component 6 can improve the smoothness of the lateral movement of the inner box 2.1, making the use and operation of the material box 2 smoother and more convenient.

[0057] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
