Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mining engineering, and in particular relates to a trolley for transporting supporting materials based on gob-side tunnel retaining. Background Art
[0002] When the working face is mined, the return air tunnel is left along the empty lane. During the temporary support of the gangue and the installation of the single + I-beam shed, the transport vehicles cannot enter due to the limited space between the advance support area and the end support of the working face. Support materials such as 11# I-beam and U29 steel are usually transported manually, which is not only time-consuming and labor-intensive, but also has low work efficiency. It also requires 2-3 people to cooperate in transportation, with a low safety factor during transportation and is prone to transportation safety accidents due to the small space. Utility Model Content
[0003] The main purpose of the utility model is to provide a trolley for transporting supporting materials based on gob-side tunnel retaining, aiming to effectively reduce the input of personnel, improve the efficiency of transport work, and reduce safety accidents during transportation.
[0004] To this end, the utility model provides a trolley for transporting supporting materials along the goaf, comprising a frame, a pair of wheels being symmetrically provided on both sides of the bottom of the frame, two pushing handles arranged horizontally side by side being provided at the rear end of the frame, a first bracket being fixedly mounted on the two pushing handles, a second bracket being provided on the top of the frame, a first bracket being formed on the first bracket for supporting the rear end of the supporting material, a second bracket being formed on the second bracket for supporting the front end of the supporting material, and the rear end of the first bracket and the front end of the second bracket being both closed.
[0005] Specifically, the first bracket is fixed to the pushing handle by a first fastening bolt.
[0006] Specifically, the pushing handle is provided with a plurality of threaded holes that can be matched with the first fastening bolts, and the plurality of threaded holes are distributed at equal intervals along the extending direction of the pushing handle.
[0007] Specifically, the second bracket is fixed to the vehicle frame by a second fastening bolt.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] 1. Labor-saving and efficient
[0010] By utilizing the lever principle, a single person can carry materials, which is labor-saving and highly efficient.
[0011] 2. Save people
[0012] One person can complete the transportation of large support materials, reducing labor and achieving the goal of saving manpower.
[0013] 3. Security
[0014] When multiple people carry materials, lifting, transporting and unloading are not synchronized, which can easily lead to safety accidents. This problem does not exist when one person is carrying materials, thus achieving the purpose of safe transportation. In addition, the tail end of the first bracket and the front end of the second bracket are both closed, which can also effectively prevent the supporting materials from sliding off the trolley during transportation, further improving the safety of transportation.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0022] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0023] See also Figure 1-Figure 3 The supporting material transport trolley for retaining tunnels along the goaf comprises a frame 1, a pair of wheels 2 are symmetrically arranged on both sides of the bottom of the frame 1, two horizontally arranged side-by-side pushing handles 3 are arranged at the rear end of the frame 1, a first bracket 4 is fixedly mounted on the two pushing handles 3, a second bracket 5 is arranged on the top of the frame 1, a first bracket 7 for supporting the rear end of the supporting material 6 is formed on the first bracket 4, a second bracket 8 for supporting the front end of the supporting material 6 is formed on the second bracket 5, and the rear end of the first bracket 7 and the front end of the second bracket 8 are both closed. When in use, a single person carries the supporting material 6, places one end in the first bracket 7, and the other end in the second bracket 8, then lifts the pushing handle 3, and pushes the transport trolley to the construction site by pushing.
[0024] In this embodiment, by utilizing the lever principle, a single person can complete the handling of the large supporting material 6, which can reduce labor and achieve the purpose of saving manpower, and can also effectively solve the problem of safety accidents that may occur when multiple people are carrying the material in an unsynchronized manner. In addition, the tail end of the first bracket 7 and the front end of the second bracket 8 are both closed, which can also effectively prevent the supporting material 6 from sliding off the trolley during transportation, and can further improve the safety of the transportation process.
[0025] See also Figure 2 and Figure 3 The first bracket 4 is fixed to the push handle 3 by a first fastening bolt 9, and the second bracket 5 is fixed to the frame 1 by a second fastening bolt 10. Of course, it can also be fixed to the push handle 3 or the frame 1 by welding or the like.
[0026] See also Figure 3 In some embodiments, the push handle 3 is provided with a plurality of threaded holes 11 that can be matched with the first fastening bolts 9. The plurality of threaded holes 11 are evenly spaced along the extension direction of the push handle 3, and the positions of the threaded holes 11 on the two push handles 3 correspond to each other. In this embodiment, the position of the first bracket 4 can be adjusted by simply screwing the first fastening bolts 9 into the corresponding threaded holes 11 and fixing the first bracket 4 on the push handle 3, that is, the spacing between the first bracket 4 and the second bracket 5 can be flexibly adjusted. Such a design enables the entire transport trolley to transport support materials 6 of different lengths, and the application range of the entire transport trolley is effectively expanded.
