Description

Technical Field

[0001] The utility model relates to the technical field of special operations of locomotives, in particular to a sand loading device for railway diesel locomotives. Background Technique

[0002] The locomotive sanding device refers to a device that sands the rail surface of the locomotive. By sanding, the adhesion coefficient between the wheel and the rail can be increased to increase the adhesion traction and prevent wheel spin, and prevent the locomotive wheels from sliding relative to the rail. The locomotive sanding device includes a sand box, which can store a certain amount of dry sand. With multiple sanding operations, the capacity of dry sand in the sand box gradually decreases, and thus sand loading is required, that is, new dry sand is refilled into the sand box.

[0003] Restricted by the environment of the track where the locomotive stops, dry sand cannot be directly unloaded near the locomotive. Therefore, a small trolley commonly used at the construction site is needed to load dry sand. The dry sand is continuously transported to the locomotive sand box by the trolley, and then workers use shovels to shovel the sand and pour it into the sand box through the sand box opening. It can be seen from this that workers need to transport dry sand back and forth and shovel it, resulting in a large labor intensity; manual filling of dry sand requires a lot of time and low work efficiency; moreover, when shoveling sand and pouring it through the sand box opening, the dry sand is likely to spill, and subsequent cleaning is also required. Summary of the Invention

[0004] In order to solve the problems of large labor intensity and low work efficiency in manual sand loading operation, the utility model provides a sand loading device for railway diesel locomotives. The electric flat car drives the sand hopper to flexibly move to the locomotive sand box. The sand hopper can unload sand into the sand box through a pipeline, thereby realizing automatic sand loading of the sand box, greatly reducing the labor intensity, and at the same time accelerating the sand loading operation.

[0005] In order to achieve the above object, the technical solution adopted by the utility model is:

[0006] A sand loading device for railway diesel locomotives includes an electric flat car, a lifting platform, a sand hopper filled with dry sand, and a sand outlet pipe for the dry sand to flow out.

DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings:

[0026] like Figures 1 to 6 As shown, a sand loading device for a railway diesel locomotive comprises an electric flatbed car 1, a lifting platform 2, a sand hopper 3 containing dry sand, and a sand outlet pipe 4 for the dry sand to flow out. Figure 1 The electric flatbed truck 1 is a reverse-riding electric four-wheeled flatbed truck, and the electric flatbed truck 1 can be manually ridden and controlled.

[0027] The electric flatbed truck 1 includes a vehicle body 101, a driving wheel set 102, a steering wheel set 103, a battery pack 104, a seat 105, an operation handle 106, and a footrest 107, as Figure 2 shown. The steering wheel set 103 and the driving wheel set 102 are respectively arranged at the front and rear under the vehicle body 101. The steering wheel set 103 adopts a front axle assembly, and the steering wheel set 103 is used for the steering control of the electric flatbed truck 1. The driving wheel set 102 adopts an electric drive axle assembly, and the driving wheel set 102 provides the running power of the electric flatbed truck 1.

[0028] A battery pack 104 is also arranged in the middle under the vehicle body 101. The battery pack 104 is connected to the driving wheel set 102 to supply power to the electric flatbed truck 1. At the same time, a seat 105, an operation handle 106, and a footrest 107 are arranged at the rear of the vehicle body 101. The driver can sit on the seat 105, place the feet on the footrest 107, and control the running of the electric flatbed truck 1 through the operation handle 106. The operation handle 106 adopts the handlebar of a common electric bicycle on the market, which can control the running speed of the electric flatbed truck 1. Moreover, a steering rod is arranged between the operation handle 106 and the steering wheel set 103. Under the linkage of the steering rod, the direction of the steering wheel set 103 is controlled, and then the traveling direction of the electric flatbed truck 1 is changed.

[0029] A lifting platform 2 is arranged above the electric flatbed truck 1. The lifting platform 2 is a scissor-type hydraulic lift. A sand hopper 3 is arranged above the lifting platform 2. Furthermore, the electric flatbed truck 1 is connected through the lifting platform 2 and the sand hopper 3. When the lifting platform 2 operates, it can drive the sand hopper 3 to move up and down.

[0030] The sand hopper 3 includes a sand hopper body 31 and a support frame 32. The sand hopper body 31 is arranged above the support frame 32. The support frame 32 is used to carry the sand hopper body 31, as Figure 3 and Figure 4 shown. The support frame 32 is a steel structure frame welded by channel steel. The support frame 32 includes a bottom frame 321, side rods 322, and reinforcing rods 323. The bottom frame 321 is a rectangular plate frame. The side rods 322 are vertically arranged around the bottom frame 321. Four side rods 322 are used to connect the four sides of the sand hopper body 31, and at the same time, the four side rods 322 are also used to support the sand hopper body 31. To ensure the reliability of the support, reinforcing rods 323 are also arranged between both sides of the bottom frame 321 and the sand hopper body 31. The reinforcing rods 323 on each side are arranged in a shape of an eight.

[0031] The lower part of the sand hopper 3 is in an inverted conical structure, that is, the sand hopper body 31 is open at the upper end, and the cross-section above the sand hopper body 31 is larger than that below. In this way, the inlet of the sand hopper body 31 is large and the outlet is small. And because the side wall of the lower part of the sand hopper 3 is inclined, the dry sand in the sand hopper 3 naturally flows towards the lowest part of the sand hopper 3.

[0032] A vibrating motor 5 is arranged below the sand hopper 3, that is, the vibrating motor 5 is arranged below the sand hopper body 31. The vibrating motor 5 accelerates the flow of dry sand. For the convenience of equipment control, an electric control box 6 for controlling the operation of the lifting platform 2 and the vibrating motor 5 is also arranged above the lifting platform 2, and the battery pack 104 also supplies power to the vibrating motor 5. The sand hopper 3 is communicated with a sand outlet pipe 4 below, that is, the sand hopper body 31 is communicated with the sand outlet pipe 4, and the sand outlet pipe 4 extends obliquely downward to the front of the electric flatbed truck 1, so that the flowing dry sand can flow out from the sand outlet pipe 4.

[0033] The sand outlet pipe 4 includes a metal hard pipe 41, a plastic hose 42 and a switching component 7 for controlling the on-off of the metal hard pipe 41. The metal hard pipe 41 is made of steel pipe. One end of the metal hard pipe 41 is communicated with the sand hopper 3, and the other end of the metal hard pipe 41 is communicated with the plastic hose 42. The plastic hose 42 is made of plastic corrugated pipe and can be bent. The plastic hose 42 is installed on the metal hard pipe 41 by a pipe clamp.

[0034] In order to facilitate the control of the entire sand outlet pipe 4, a switching component 7 is also arranged on the metal hard pipe 41. The switching component 7 includes an opening 71 and a sand locking knife 72. An opening 71 is opened on the metal hard pipe 41. The opening 71 is a semi-circular notch formed along the side wall of the metal hard pipe 41. A sand locking knife 72 is also rotatably arranged on the metal hard pipe 41, as Figure 5 and Figure 6 shown.

[0035] The sand locking knife 72 is arranged in the opening 71, and the sand locking knife 72 can be manually operated to rotate and be arranged inside and outside the opening 71. The sand locking knife 72 includes an opening and closing section 721 and a handle section 722. The opening and closing section 721 is a circular plate structure. The cross section of the opening and closing section 721 matches the cross section of the metal hard pipe 41, and can effectively close the metal hard pipe 41. The handle section 722 is integrally formed with the opening and closing section 721. The handle section 722 is tangent to the opening and closing section 721, and the handle section 722 is convenient for controlling the rotation of the sand locking knife 72.

[0036] The principle of the utility model is as follows: First, load dry sand into the sand hopper 3, and then manually ride the electric flatbed truck 1 to drive the sand hopper 3 to the position of the locomotive sand box. Operate the lifting platform 2 to run through the electric control box 6 to drive the sand hopper 3 to move upward, so that the position of the sand hopper 3 is higher than the locomotive sand box. Insert the plastic hose 42 into the sand box to realize the connection between the sand outlet pipe 4 and the sand box. Manually rotate the sand locking knife 72 upward to no longer close the metal hard pipe 41, and then operate the electric control box 6 to start the vibrating motor 5. Then, the dry sand in the sand hopper 3 will continuously be transported into the locomotive sand box along the sand outlet pipe 4, realizing an automatic and fast sand loading operation. After the sand loading operation, turn off the vibrating motor 5 and reverse the sand locking knife 72 to close the metal hard pipe 41.

[0037] The upper sand operation of the utility model is convenient and fast, without consuming a large amount of labor. Under the vibration action, dry sand can naturally flow out of the sand hopper 3 and enter the locomotive sand box through the sand outlet pipe 4, realizing rapid sand addition, improving the sand addition efficiency, reducing the labor intensity, and having good practicability. It can be more rapid, efficient and convenient in actual production, achieving the purpose of saving time and effort, greatly reducing the sand loading time of the locomotive, and improving the maintenance efficiency of the locomotive.

[0038] It should be noted that: since the metal hard pipe 41 is provided with an opening and closing port 71, after the sand locking knife 72 is opened and the opening and closing port 71 is completely opened, dry sand may flow out through the opening and closing port 71 during the process of flowing through the metal hard pipe 41, and thus sand leakage may occur. At this time, the sand leakage situation can be avoided by controlling the flow rate of dry sand, that is, reducing the amount of dry sand entering the metal hard pipe 41. Specifically, it can be achieved by reducing the size of the inlet of the metal hard pipe 41: designing the original circular inlet of the metal hard pipe 41 as a semi-circular shape. In this way, dry sand will not fill the entire cross-section of the metal hard pipe 41, and the sand leakage phenomenon can be prevented.

[0039] The above-described embodiments are only the preferred embodiments of the utility model, and do not limit the scope of implementation of the utility model. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the utility model patent should be included in the scope of the utility model patent application.
