Description

Technical Field

[0001] The utility model relates to the technical field of tamping machines, in particular to a rear casing of a tamping machine which is convenient for replacing a starting battery. Background Art

[0002] Internal combustion impact tamping picks are now widely used in my country's railway system for ballasted railway maintenance, especially for tamping operations on turnouts and branch lines. The switch from manual to electric starting significantly reduces the labor intensity of the starting process and ensures stable and timely engine starts. However, existing electric starting devices suffer from the time-consuming and labor-intensive installation, charging, and replacement of the starting battery. Furthermore, the battery can only be charged internally, posing a safety hazard.

[0003] Therefore, a device that can quickly and easily install and replace the starting battery and can conveniently and quickly complete the battery external charging needs to be proposed. Utility Model Content

[0004] In view of this, in order to solve the problems existing in the technical background, the present invention proposes a tamping machine rear housing that is convenient for replacing the starting battery. The specific technical solution is as follows:

[0005] A tamping machine rear housing that facilitates replacement of a starting battery comprises the tamping machine rear housing, wherein an outer wall of the tamping machine rear housing is provided with a battery compartment, wherein a starting battery is disposed in the battery compartment, wherein the starting battery is electrically connected to a starting motor controller via a socket and a power button for powering the starting motor controller, wherein the starting motor controller is disposed on the inner side of the tamping machine rear housing, wherein the battery compartment is provided with an adapted battery compartment cover, wherein the battery compartment cover 3 is fastened to the tamping machine rear housing with screws;

[0006] The rear casing of the tamping machine has four mounting holes, and steel T-shaped washers are provided in the mounting holes. The outer edge of the small end of the T-shaped washer is conical, and its small end diameter is slightly smaller than the inner diameter of the four mounting holes of the rear casing 1 of the tamping machine, forming a conical ridge in the middle.

[0007] Furthermore, a battery drawstring is provided in the middle of the starting battery, and the starting battery 6 is installed into the battery compartment on the rear housing of the tamping machine by grabbing the battery drawstring.

[0008] Furthermore, the large diameter of the conical ridge is slightly larger than the inner diameter of the four mounting holes of the rear casing of the tamping machine. The T-shaped washer is pressed into the four mounting holes of the rear casing of the tamping machine. The shoulder of the T-shaped washer is close to the bottom of the countersunk hole of the mounting hole of the rear casing of the tamping machine 1 to transmit the clamping force of the mounting screw and increase the force area and protect the bottom of the countersunk hole of the mounting hole of the rear casing of the tamping machine from being scratched when the mounting screw is tightened.

[0009] Furthermore, after the T-shaped washer is pressed into the four mounting holes of the rear casing of the tamping machine, the conical ridges are embedded into the inner walls of the mounting holes of the rear casing of the tamping machine to prevent the rear casing of the tamping machine from falling off when the rear casing of the tamping machine is disassembled.

[0010] Furthermore, after the starting battery is installed in the battery compartment, the battery output charging plug is inserted into the socket.

[0011] The above technical solution has the following beneficial effects:

[0012] The utility model mounts the rear housing of the tamping machine onto an electrically started internal combustion impact tamping pick, installs the starting battery, plugs in the battery output charging plug, and secures the battery compartment cover with screws. To charge the starting battery, the battery compartment cover is removed, the battery output charging plug is unplugged, and the starting battery is pulled out of the battery compartment by pulling the battery strap. During the charging process, the starting battery remains well ventilated and visible throughout, minimizing safety hazards during the charging process. The utility model allows for quick and easy installation and replacement of the starting battery, as well as convenient and efficient off-site battery charging. It can be used in railway, highway, and municipal construction and maintenance operations for operations such as ballast tamping, foundation compaction, and surface crushing.
