[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown in the figure, a multi-functional quick-change service vehicle for mining includes a front end 1 and a chassis 2 arranged at the front and rear. A tipper frame 3 is rotatably mounted on the chassis 2. A quick-change controller 5 is detachably installed at the front end of the chassis 2 through a quick-release mechanism 4. The quick-change controller 5 is connected to the chassis 2 through a telescopic connecting rope 6.

[0025] In this embodiment, both the cab 1 and the chassis 2 are commercially available mining truck cabs and chassis.

[0026] In this embodiment, the quick-change controller 5 is connected to the service vehicle via a telescopic connecting rope 6, allowing the operator to hold the quick-change controller 5 away from the service vehicle to perform quick-change operations, thus improving the flexibility of using the quick-change controller 5.

[0027] In this embodiment, the quick-change controller 5 is externally mounted. The operator can control the loading and unloading of the loading unit by standing near the service vehicle and holding the quick-change controller 5. The operator has a very good field of vision and can complete the loading and unloading of the loading unit efficiently and accurately.

[0028] Moreover, compared to structures where control operations are performed from inside the cab, this invention requires only one person to complete the loading and unloading of the loading unit, thus saving labor costs and loading / unloading time.

[0029] like Figure 2 , Figure 3 and Figure 5 As shown in the diagram, the quick-change controller 5 includes a quick-change control handle 501 and an engine remote speed control switch 502, which is electrically connected to the engine 101 of the vehicle front 1.

[0030] In this embodiment, the engine remote speed control switch 502 is used in conjunction with the remote throttle system, enabling the operator to control the engine speed 101 from a position away from the driver's cab.

[0031] In this embodiment, both the engine remote speed control switch 502 and the remote throttle system are commercially available models (such as remote speed controllers for Cummins engines, wireless electronic throttle systems produced by Tianma Company, etc.). Their working, installation and connection principles are all existing technologies and are well known to those skilled in the art, and will not be described in detail here.

[0032] In this embodiment, the quick-change control handle 501 includes multiple control buttons for controlling functions such as start, stop, speed adjustment, and direction change. The connection relationship and principle between the control buttons, the tipping cylinder 201, and the quick-change assembly 202 are all existing technologies and are well known to those skilled in the art, and will not be described in detail here.

[0033] The chassis 2 has a vertically arranged fixed plate 503 at its front end. The two ends of the telescopic connecting rope 6 are fixedly installed on the fixed plate 503 and the chassis 2 respectively. The lower end of the fixed plate 503 is installed on the chassis 2 through the quick-release mechanism 4. The upper end of the fixed plate 503 is fixed with a protective box 504. The quick-change control handle 501 is located inside the protective box 504. The lower part of the protective box 504 is provided with a mounting bracket 505. The engine remote speed control switch 502 is installed on the mounting bracket 505.

[0034] In this embodiment, the protective box 504 is provided to protect the quick-change control handle 501, preventing accidental impact from falling or splashing stones, thus improving the reliability and safety of this invention.

[0035] Furthermore, the quick-release mechanism 4 includes a fixing hole group and a mounting hole group. The fixing hole group includes a number of fixing holes 401 that are equidistantly spaced on the fixing plate 503, and the mounting hole group includes a number of mounting holes 402 that are equidistantly spaced on the chassis 2. The mounting holes 402 and the fixing holes 401 are arranged in a one-to-one correspondence. A locking pin 403 is inserted into each mounting hole 402 and the corresponding fixing hole 401.

[0036] like Figure 4 and Figure 5 As shown, the end of the tipper frame 3 away from the front 1 is hinged to the chassis 2, and the other end of the tipper frame 3 is hinged to the chassis 2, with a tipper cylinder 201. A quick-change assembly 202 extending along the length of the tipper frame 3 is installed on the tipper frame 3. The quick-change assembly 202 is used to load and unload the loading unit.

[0037] In this embodiment, each loading unit of the quick-change service vehicle is provided with a quick-change chassis 7 at the bottom. The structure of the quick-change chassis 7 is adapted to the quick-change component 202, and it can be loaded onto or unloaded from the dump truck frame 3 through the quick-change component 202.

[0038] In this embodiment, the quick-change assembly 202 includes a towing hook (not shown in the figure) that is slidably mounted on the dump truck frame 3 along the length of the dump truck frame 3. The towing hook is used to hook onto the crossbeam on the quick-change chassis 7, and the towing hook is pulled by the towing cylinder 203.

[0039] Meanwhile, a limit switch 204 can be installed at the front end of the dump truck frame 3 to detect the position of the quick-change chassis 7, so as to ensure the accuracy and safety of the loading unit installation.

[0040] In this embodiment, the structure, installation relationship and connection principle of the traction hook and traction cylinder 203 are all existing technologies and are well known to those skilled in the art, and will not be described in detail here.

[0041] In addition, the quick-change control handle 501 is electrically connected to the tipping cylinder 201 and the quick-change assembly 202.

[0042] The procedure for loading and unloading the loading unit of the service vehicle using this utility model is as follows:

[0043] The first step is to start the tipping cylinder 201 by using the corresponding button on the quick-change control handle 501, and to control the piston rod of the tipping cylinder 201 to extend outward, driving the tipping frame 3 to gradually rotate and rise to a suitable height near the front end of the truck head 1.

[0044] The second step is that after the front end of the dump truck frame 3 is raised to the preset position, the dump cylinder 201 stops.

[0045] The third step is to control the traction cylinder 203 of the quick-change assembly 202 to start by using the corresponding button on the quick-change control handle 501, and control the piston rod of the traction cylinder 203 to extend outward, pushing the quick-change chassis 7 on the dump truck frame 3 to move backward, and the quick-change chassis 7 gradually detaches from the dump truck frame 3.

[0046] Fourth step, drive the service vehicle to the new loading unit location, align the rear end of the dump truck frame 3 with the quick-change chassis 7 of the new loading unit, and hook the tow hook onto the crossbeam of the quick-change chassis 7.

[0047] Fifth step, control the piston rod of the traction cylinder 203 to retract inward by using the corresponding button on the quick-change control handle 501, pull the loading unit on the ground toward the tipper frame 3 and pull it onto the tipper frame 3;

[0048] Step 6: When the piston rod of the traction cylinder 203 is fully retracted, the loading unit has not been fully moved onto the dump truck frame 3. The operator can control the piston rod of the traction cylinder 203 to fully extend again, hook the towing hook onto the crossbeam of the quick-change chassis 7 again, and then control the piston rod of the traction cylinder 203 to retract inward again to continue pulling the loading unit to move.

[0049] The seventh step involves using the corresponding button on the quick-change control handle 501 to control the piston rod of the tipper cylinder 201 to retract inward, thereby controlling the tipper frame 3 to rotate and fall to a horizontal position.

[0050] Step 8: The front end of the quick-change chassis 7 on the loading unit contacts the limit switch 204 on the dump truck frame 3. The limit switch 204 can directly control the traction cylinder 203 to stop, and the loading unit is installed in place.

[0051] Step 9: The operator uses fasteners such as fixing pins to secure the quick-change chassis 7 to the dump truck frame 3.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
