Description

A type of truck-mounted mining car boom and loader Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and more specifically, to a working arm for a vehicle-mounted mining truck. Furthermore, this utility model also relates to a loader including the aforementioned working arm for a vehicle-mounted mining truck. Background Technology

[0002] To ensure the stability of the mine car during transportation, it must first be lifted from the bottom before transportation, so that its wheels are suspended in the air, thereby preventing the mine car from moving during transportation.

[0003] However, mine cars are heavy and difficult to lift by manpower. Using other lifting or hoisting machinery can only lift the mine car, but it is impossible to lock the mine car during transportation or to overturn it. When dealing with garbage, waste, and materials inside the mine car, a lot of manpower or other equipment is still required for auxiliary operations, which is inefficient and poses safety risks.

[0004] In conclusion, how to solve the problem of mine cars being unable to be fixed and rotated is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a working arm for loading mine cars, which drives the front locking block and the rear locking block to move relative to each other through the telescopic component, thereby locking the mine car to the working arm body. At the same time, the working arm body is connected to the loader, and the working arm body is driven by the loader to achieve the tilting of the mine car, thereby improving work efficiency and eliminating safety hazards.

[0006] Another objective of this utility model is to provide a tool that includes the above-mentioned vehicle-mounted mining truck boom and loader, has the same technical features, and can solve the same technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A truck-mounted mining truck boom includes:

[0009] The working arm has a pin hole at its first end for rotatably connecting with the loader via a positioning pin, and a sliding groove at its second end.

[0010] The front locking block is slidably installed with the slide groove;

[0011] The rear locking block is fixedly installed relative to the working arm body;

[0012] The telescopic assembly has one end fixedly connected to the working arm body and the other end fixedly connected to the front locking block, and is used to drive the front locking block away from or towards the rear locking block.

[0013] Preferably, the rear locking block is fixedly connected to the first end of the working arm body, and the length direction of the slide groove is consistent with the length direction of the working arm body.

[0014] Preferably, the working arm body has a hollow structure, and the telescopic component is fitted inside the working arm body.

[0015] Preferably, the telescopic assembly includes a hydraulic cylinder, the cylinder body of which is hinged to the working arm body via a hydraulic cylinder positioning pin, and the piston rod of which is fixedly connected to the front locking block via a thread.

[0016] Preferably, the side wall of the working arm is provided with a through hole for passing through the hydraulic oil pipes connecting both ends of the cylinder.

[0017] Preferably, the telescopic assembly includes a lead screw and a motor that drives the lead screw to rotate. The lead screw is rotatably mounted to the working arm body, and the motor is fixedly mounted relative to the working arm body. A lead screw nut that meshes with the lead screw is provided in the front locking block.

[0018] Preferably, the top of the front locking block and the rear locking block are provided with locking hooks with opposite openings for locking the bottom side beam of the mine car.

[0019] A loader comprising the working arm of a mining truck as described in any one of the above claims.

[0020] Preferably, a drive assembly is provided between the body of the loader and the working arm for driving the working arm to rotate around the working arm positioning pin.

[0021] The vehicle-mounted mining truck boom provided by this utility model has at least the following advantages compared with the prior art:

[0022] The telescopic assembly drives the front locking block and the rear locking block to move relative to each other, thereby locking the mine car from both sides and thus locking the mine car and the working arm together. Therefore, the movement of the mine car is effectively prevented during transportation.

[0023] Meanwhile, the boom and the loader are rotatably connected through the boom positioning pin, so the boom and the loader can rotate relative to each other. That is, when the boom is driven to rotate by the drive mechanism inside the loader, the mine car can be driven to rotate synchronously, thus realizing the tilting of the mine car, improving work efficiency, and eliminating safety hazards during manual operation.

[0024] The loader provided by this utility model includes the above-mentioned vehicle-mounted mining truck working arm and has the same beneficial effects. Attached Figure Description

[0030] 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.

[0031] The core of this utility model is to provide a working arm for loading mine cars. By driving the front locking block and the rear locking block to move relative to each other through the telescopic component, the mine car can be locked to the working arm. At the same time, the working arm is connected to the loader. With the help of the loader to drive the working arm to move, the mine car can be flipped, thereby improving work efficiency and eliminating safety hazards.

[0032] Another core aspect of this utility model is to provide a working arm and loader for a mining truck that include the above-mentioned vehicle-mounted loading machine, which have the same technical features and can solve the same technical problems.

[0033] Please refer to Figures 1 and 2. A type of truck-mounted mining truck boom includes:

[0034] The working arm 11 has a pin hole at its first end for rotating connection with the loader via the working arm positioning pin 10, and a slide groove 12 at its second end.

[0035] Front locking block 1 is slidably installed with slide groove 12;

[0036] The rear locking block 8 is fixedly installed relative to the working arm body 11;

[0037] The telescopic assembly has one end fixedly connected to the working arm body 11 and the other end fixedly connected to the front locking block 1, and is used to drive the front locking block 1 away from or close to the rear locking block 8.

[0038] As shown in Figure 1, a rear locking block 8 is fixedly installed on the working arm 11, and a front locking block 1 is slidably installed on the working arm 11. A telescopic assembly is provided to drive the front locking block 1 and the rear locking block 8 to move relative to each other. In use, after the working arm 11 is rotated and installed with the loader, the working arm 11 is extended under the mine car, and the rear locking block 8 is engaged with the side beam on one side of the bottom of the mine car. Then, the telescopic assembly drives the front locking block 1 to retract and engage with the side beam on the other side of the bottom of the mine car, thereby locking the mine car and the working arm 11. The loader then loads and transports the mine car, or the working arm 11 and the mine car are rotated synchronously by the drive mechanism inside the loader.

[0039] When the mine car needs to be separated from the working arm 11, the telescopic component extends, causing the front locking block 1 to move forward and away from the rear locking block 8, thereby causing the front locking block 1 to separate from the side beam at the bottom of the mine car. Then the working arm 11 is moved so that the rear locking block 8 separates from the side beam on the other side of the bottom of the mine car, thus achieving the separation of the mine car from the working arm 11.

[0040] The front locking block 1 is slidably installed in the slide groove 12 inside the working arm body 11, so the front locking block 1 has a relatively stable movement trajectory when driven by the telescopic component.

[0041] Meanwhile, the front locking block 1 and the rear locking block 8 are preferably in the form of hooks, pins, etc. When they come into contact with the mine car, they can be connected and fixed to the mine car. For example, the front locking block 1 and the rear locking block 8 both adopt hook structures, which hook the side beams at the bottom of the mine car from both sides, thereby locking the mine car and the working arm 11. When it is necessary to separate the mine car from the working arm 11, the telescopic component drives the front locking block 1 away, so the hook of the front locking block 1 separates from the side beam of the mine car. The working arm 11 is retracted under the action of the loader, so that the hook of the rear locking block 8 separates from the side beam of the mine car, thereby separating the mine car from the working arm 11.

[0042] Alternatively, the front locking block 1 and the rear locking block 8 may adopt a pin structure, and have an internal drive mechanism for extending and retracting the pin. Pin holes are reserved at corresponding positions on the bottom of the mine car. When the front locking block 1 and the rear locking block 8 move to the corresponding positions on the bottom of the mine car, the drive mechanism drives the pin to extend and engage with the pin holes at the corresponding positions on the mine car, thereby locking the mine car and the working arm 11. When it is necessary to separate the mine car and the working arm 11, the drive mechanism controls the pin to retract and separate from the pin holes. The telescopic component drives the front locking block 1 away, and then the working arm 11 retracts, thereby separating the mine car and the working arm 11. Preferably, the extension and retraction direction of the pin is perpendicular to the length direction of the working arm 11.

[0043] In some embodiments, the rear locking block 8 is fixedly connected to the first end of the working arm 11, and the length direction of the slide groove 12 is consistent with the length direction of the working arm 11.

[0044] As shown in Figure 1, the rear locking block 8 is fixed to one end of the working arm 11, while the front locking block 1 is slidably disposed at the other end of the working arm 11. The sliding direction of the front locking block 1 is consistent with the length direction of the working arm 11. Therefore, when the working arm 11 is inserted into the bottom of the mine car, it can lock or disengage the rear locking block 8 from the mine car by moving along its own length direction.

[0045] Then, the front locking block 1 is driven to move by the telescopic component, so as to lock or disengage the front locking block 1 from the mine car.

[0046] In some embodiments, the sliding direction of the front locking block 1 is perpendicular to the length direction of the working arm 11. When the rear locking block 8 contacts and locks with the mine car, the front locking block 1 moves perpendicular to the length direction of the working arm 11 and is inserted into the corresponding pin hole of the mine car in the form of a pin, restricting the movement of the mine car, thereby achieving the locking of the front locking block 1 with the mine car.

[0047] In some embodiments, the working arm 11 has a hollow structure, and the telescopic component is fitted inside the working arm 11.

[0048] As shown in Figure 1, the working arm 11 has a hollow structure. The telescopic component is built into the hollow structure of the working arm 11, which can effectively prevent falling objects from the mine car from directly contacting the telescopic component, thereby preventing the telescopic component from being damaged and extending its service life. At the same time, it can also prevent falling objects from the mine car from causing the telescopic component to jam, thus ensuring the stability of the equipment.

[0049] Moreover, as shown in Figure 2, the slide 12 passes through the through groove on the top surface of the working arm 11, and the main body of the front locking block 1 is also set inside the hollow structure of the working arm 11. Only the locking part of the front locking block 1, such as the hook, passes through the slide 12 and is located outside the working arm 11, which facilitates contact and locking with the mine car.

[0050] In some embodiments, the telescopic assembly includes a hydraulic cylinder, the cylinder body 3 of which is hinged to the working arm body 11 via a hydraulic cylinder positioning pin 9, and the piston rod 2 of which is fixedly connected to the front locking block 1 via a thread.

[0051] As shown in Figure 1, the telescopic assembly includes a hydraulic cylinder, wherein the front end of the piston rod 2 of the hydraulic cylinder is fixedly connected to the front locking block 1 by a thread, and the cylinder body of the hydraulic cylinder is hinged to the working arm body 11 by the hydraulic cylinder positioning pin 9. When there is an error in the movement trajectory of the front locking block 1, the hydraulic cylinder can rotate slightly around the hydraulic cylinder positioning pin 9 to avoid the movement of the front locking block 1 being jammed.

[0052] In some embodiments, the side wall of the working arm 11 is provided with a through hole for passing through the hydraulic oil pipes connecting both ends of the cylinder 3.

[0053] As shown in Figure 1, a front rectangular hole 4 and a rear rectangular hole 6 are provided on the side wall of the working arm 11, which are used to pass through the front hydraulic oil pipe 5 and the rear hydraulic oil pipe 7 connected to the front and rear ends of the cylinder body 3, respectively. By setting the through hole on the side wall of the working arm 11, it is possible to effectively prevent debris falling from the mine car from entering the interior of the working arm 11 through the through hole.

[0054] In some embodiments, the telescopic assembly includes a lead screw and a motor that drives the lead screw to rotate. The lead screw is rotatably mounted to the working arm 11, and the motor is fixedly mounted relative to the working arm 11. A lead screw nut that meshes with the lead screw is provided in the front locking block 1.

[0055] The telescopic assembly includes a lead screw and a motor that drives the lead screw to rotate. The motor is fixedly connected to the working arm 11, and the front locking block 1 is provided with a lead screw nut that meshes with the lead screw. The lead screw is rotatably mounted to the working arm 11. During operation, the motor drives the lead screw to rotate, and the lead screw meshes with the lead screw nut, thereby driving the front locking block 1 to move relative to the working arm 11.

[0056] In some embodiments, the tops of the front locking block 1 and the rear locking block 8 are provided with locking hooks with opposite openings for locking the bottom side beams of the mine car.

[0057] As shown in Figure 1, the front locking block 1 and the rear locking block 8 are provided with locking hooks with opposite openings at their tops. When the working arm 11 extends into the bottom of the mine car, the front locking block 1 and the rear locking block 8 approach the mine car from both sides, thereby enabling the locking hooks to engage and lock the side beams at the bottom of the mine car from both sides.

[0058] In addition to the vehicle-mounted mining truck working arm disclosed in the above embodiments, this utility model also provides a loader including the above-mentioned vehicle-mounted mining truck working arm. A drive assembly is provided between the body of the loader and the working arm 11 for driving the working arm 11 to rotate around the working arm positioning pin 10.

[0059] The drive assembly is preferably a telescopic rod or a drive motor. If the drive assembly is a telescopic rod, the two ends of the telescopic rod are respectively hinged to the middle of the loader body and the working arm. When the telescopic rod is extended or shortened, it can drive the working arm 11 to rotate around the working arm positioning pin 10, that is, drive the working arm 11 to rotate relative to the machine body.

[0060] Alternatively, the drive component may be a drive motor, with the main body of the drive motor fixedly connected to the machine body. The output shaft of the drive motor is directly or through a gearbox fixedly connected to the working arm 11. The connection position between the output shaft of the drive motor or gearbox and the working arm 11 is coaxial with the positioning pin 10 of the working arm. That is, when the drive motor rotates, it can drive the working arm 11 to rotate relative to the machine body.

[0061] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0062] The above provides a detailed description of the vehicle-mounted mining truck boom and loader provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
